Question
I was about have unprotected sex with my bf. We just started and his foreskin tore(not sure why) and started bleeding. we stopped immediately. But some of his blood went inside my vagina. its been 36hours since then. i was about to take an emergency pill but i got my periods(earlier than expected). Now i am not sure if i should take the pill. Are there still chances of me getting pregnant? Should i take the pill even though i got my periods? i do not think any sperm went in but not sure. I am very confused. Please advice

Brief Answer:
No need to take the pill.

Detailed Answer:
Hello,
Thanks for trusting us with your health concern.
The entry of blood from penis into vagina does not cause a pregnancy. The chances of sperms depositing inside vagina without an actual penetration is almost zero.
Now that your bleeding for periods has started there is no need to take an emergency contraceptive pill now. It was your safe period of the cycle. The earlier than expected period can happen due to stress and anxiety related to the incident.
Please do not worry. You are safe. There is no need to take the tablet now. But in future it is best to use a protection as emergency pills if taken frequently can cause irregular periods and protection will save you from any genital infections also.
Please feel free to discuss further. I will be glad to answer the follow up queries that you have.
Wishing you good health.
Regards.

Thank you so much for your answer. it really reduced my tension.
One last thing. He did not go inside me completely. He was like half a cm inside me when this happened. he says nothing went in but what i am worried about is if any pre sperm (i am not sure how to call that - sperm that may come before he finishes the act) went in me which may lead to pregnancy.

Brief Answer:
Pregnancy is ruled out after the periods.

Detailed Answer:
Hello.
Thanks for writing again.
Pre-ejaculatory (or pre-cum) fluid does have sperm in it but in a very, very minimal amount.

Technically speaking pre-ejaculate does not actually contain sperm in it, but can pick up leftover sperm from the man's urethra from previous ejaculations. The chances are extremely low that you will get pregnant from pre-ejaculate. Furthermore the fact that you had your periods after the episode further reduces the risk to zero.
Hope my answer is helpful.
Do accept my answer in case there are no further queries.

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!
