Question: Me and my girlfriend are 19 years old. My girlfriend had her period on 5th May. We had sex on the 19th of May. We used a condom. I pulled out before I ejaculated. The condom did not tear or break.
She hasn't had her period since then. She has had irregular periods often. She has hereditary thyroid problems and has received treatment for missed periods before in her life.
We are worried about pregnancy. What are the chances that she might be pregnant? Please help.

Detailed Answer:
Hi!
Thanks for your query.
If you have had protected intercourse even thought 19th May was her ovulation period( fertile days) ,chances for pregnancy are very very low.
Women whose partners use male condoms experience a 2% per-year pregnancy rate with perfect use.
Hence she should take a urine pregnancy test at home because we cant exclude/confirm a pregnancy.

If pregnancy test will be negative than she should contact with an endocrinologist because missed periods may be from thyroid problems.
Thyroid problems are associated with missed periods .

All the best

Thanks for your answer.
Before she takes the rest is there some way to guess? Are there any symptoms to look for that can tell either? Is the likelihood truly low if we used protection and also did not ejaculate? We have started new jobs in different cities and the stress level has been high. Could that be a factor? How late can a period be?

Brief Answer:
I don't rely on symptoms to detect pregnancy...

Detailed Answer:
Hi again!

Both the factors having thyroid problems in the past and excessive stress can cause a missed period or delay periods.

You have protected intercourse and you did not ejaculate ,chances for pregnancy almost are zero.
But to be calm both of you ,take a urine pregnancy test.

Symptoms of pregnancy and premenstrual symptoms with delayed period match each other. There is no way of differentiating it symptom wise. So don't rely on them.

Take care and don't worry

Detailed Answer:
Hi!
Thanks for your query.
Irregular bleeding with delay periods and/or metroagia (bleeding between menstrual cycles) have many causes but referring to her anamenzes that she have suffered and been treated for thyroid problems ,she should consult with endocrinologist.

If her balance of thyroid hormone is normal than she should consult with a gyn to determine he cause of irregular bleeding.

Thyroid problems are related with periods .
Treating the cause of bleeding is the best.

Take care for her and dont worry

I am really worried for I have been spotting since Oct.31, 2012. I am 20 years old who have irregular menstrual cycle. I had my last menstruation last Sept.10,2012. Had unprotected sex on Oct.12 but is sure that my boyfriend did not ejaculate inside me(But just to be sure, I had a pregnancy test last Nov.9 and it was negative). On Oct.21, I was prescribed to take Clarithromycin(an antibiotic) for 10 days due to a throat infection and on my last day of medication(Oct.31), I started having brown spotting. I do not know if the antibiotic caused this or what. It is exactly 16 days since I was spotting. I ve seen cervical mucus discharge twice, one is clear with few red in it (I think it is blood), the other is reddish. I am not experiencing any pain in my body. The spotting has no odor. I am not taking any birth control pills. These are all the info I can think of. Is my spotting normal? I am afraid I might have a disease or what. Please do reply.

Hi, I am a 31 year old female with three children. My youngest is 21 months. Over the past 9 months or so I have had very irregular menstration. My normal cycle has always been 28 days with bleeding of 7 days. I had always been regular and never had any fertility problems. I don t take birth control and haven t since 2006. Over the last 9 months I began to bleed a week early and for about 9 days. Then it increased to 11 days and then when it finally reached 14 days I made a doctor appointment. My mother and brother both have hypothyroidism and I have always had high cholesterol that even with diet and medication seldom lowers. I am 5 ft 4.5 and weigh 148 lbs. I noticed about 6 months ago my hair had extremely thinned (very drastic) and has been breaking off. I assumed it was my hair dresser s fault - maybe using cheap products. I haven t gone through anything stressful or major changes that I feel would change my menstration. When the bleeding starts its large bright red drops of blood rather than a slow pink spotting as a general warning (how it used to be). The doctor said I had no cysts or thyroid problems and he prescribed medroxyprogesterone . He told me to take it 7 days before my bleeding starts - for 3 months. Well, I have done this and nothing changed. The first 2 months it seemed to work and I was very regular, then it went back to being abnormal. It was hard to take it 7 days prior to bleeding because I would start on irregular days (way early). I have taken it for 4 months now and I just started bleeding a week early today. I m frustrated about this bleeding but I am worried something could be wrong with me. It just doesn t seem right. He had told me not to worry that everything was fine, and that more than anything this was just an annoying issue for me rather than a concern. I want to get a second opinion. Is this something to be worried about?

Hi, Im a 33yr old Indian woman, recently married. My husband and I decided on birth control pills instead of condoms so i went on the pill a month before the wedding. However the pill caused me considerable mood swings and overall uneasy feelings and i stopped after finishing the first file. Since then my period has become even more erratic than before. Its been 8months since i quit the pill and my periods have not normalized yet. I used to get 4-5 days of period with normal to heavy flow and some blood clots. Now on certain months i get heavy flow or very light flow, duration has also gone haywire...sometimes 3 days or sometimes 7. I ve also noticed blackish dry clots before the onset of my periods now which i never saw before. This month s menstruation is truly baffling me. I was due to stsrt on the 3rd week but i started spotting from the 9th of this month and my period is still on! Flow is very light to medium and has been on for past 9days! I think i should also mention that since i gave up the pill, we are not using any type of birth control. Although i m not ready to be pregnant, my husband insists on going skin to skin :-/ Its been a stressful time for me adjusting to the whole marriage setup and I ve fallen ill a number of times (usually im of pretty robust health) with colds, sore throats, stomach flus. And on top of that my periods have been giving me added tension . Please advice!
