Thank you for posting a query.

If you are taking pills regularly in this menstrual cycle, then you have practically no chance of pregnancy. Because, when the contraceptive pills are taken regularly then chance of pregnancy is less than 1%.

You should not stop taking pills. Because for its proper contraceptive action you have to continue the pill regularly as like normal cycle.

For doing a home pregnancy test, first you have to calculate the expected date of your next period. You can do the pregnancy test on or after the day of your missed period.

The pregnancy test is very much accurate. But gold standard investigation of pregnancy detection is ultrasound scan. It can be done after 5 weeks.

So, overall, you have practically no chance of pregnancy as you have taken the oral contraceptive pills regularly.

Hope this information is sufficient. Let me know, if you have any more question.

Let me be more specific i havent had a period for 2 years since ive been taking the pill continously with no breaks. I guess im just really concerned how will i make sure im not pregnant should i finish off a full month of pills and then wait to try to get a period. Since i do not know when my period will start up again since i havent had it for 2 years

Thank you for writing back.

As you described, you have not had any period for 2 years. In that case you have to finish off a full month of pills. Make sure that you have taken the pills minimum for a 15 days period from the day of intercourse. Then only you can stop and wait for 7 to 10 days for withdrawal bleeding. But you may face some problem in having a period due to hormonal imbalance caused by the pills.

In that conditions first you have to confirm that you are not pregnant by doing home pregnancy test. The test should be done on or after 21 days from the day of intercourse. After that consult with a gynecologist for forceful starting of period.

If you want to have period regularly, you should take the pill for 21 days and then give a break for 7 days. Within this 7 days you will have your period. After that you can again star your pill. It is the most healthy way to take pills.

Hi, I've been on ovranette for about four years as my dr thinks that my periods were causing my epileptic seizures, over the last few weeks I've had some bleeding every few days. I don't follow the four week cycle, I'm prescribed the pill for every day without a seven day break so why am I bleeding?

About a year ago, I started seeing white spots on my legs...they have multiplied rapidly. The dermatologist diagnosed it as Vitiligo. I am currently applying Pigmento ointment (charak). I was sent Vitiligo 30 sublingual pills from Biogetica, as well as Pigmento Tablets. I am a breast cancer survivor (2), and have had reconstruction. I am 68, and 5 4 tall...weigh 154 lbs. I am really scared to ingest the pills for fear that it will do liver damage. One of the pills contain Arsen Sulph . How harmful is this? Please advise. Thank you. Juliet

Hi me and my bf had unprotected sex last month before my period and due to my work schedule I wasn t able to visit the clinic until the following Monday which was the fifth day afterwards after I took the pill I had sore breast, hot flashes and lower back pain then I got what I thought was my period which was extremely lighter then normal and brown. Usually my period last about 6or 7 days this last time it was about 4 to 5 pasty, dark brown, and some days wouldn t bleed at all then spot the next. I took a test (a cheap 99 cent store one) and it said negative. This month it s time for me to have my period again and I have no signs of it coming. No bloating, salt craving, mood swing, sharp pains...nothing. I m not pregnant right??
