[|Human|] I have been taking ortho tri cycles for over 10 years, recently on my third week, I missed 2 pills, which was the Thursday and Friday, on sat morning, when I noticed,  I took the 2 missed pills right away, so I did not take any more pill on sat at my regular time, on Sunday I took sat. Pill and Sunday pill, I should get my period yesterday, ( wed) but till now it still did not happen, am I ok?
[|AI|]  Hi. Thanks for asking in Chat Doctor. Ortho TRI cycle contains same amount of estrogen in all 21 pills but varying doses of progesterone for every 7 tab (so called TRI cycle). For effective action, OCP should be taken at the same time every day. If you miss one pill, you should take two pills the next day at the usual time. If you miss more than 2 pills as in your case, you should discontinue the pack, go in for some other alternative method and start the next pack after you get regular period. The last 7 pills contain more amount of progesterone. So, the reason for your delayed period may either be due to increased level of progesterone or may be failure of contraceptive protection, and it is too early to come to any conclusion now. So, wait for a week and still if you don't get with Chat Doctor. I hope this is useful to you.
