Hi, Dr Purushottam Neurgaonkar here. I welcome you to HCM VIRTUAL CLINIC. I have gone through your question, and I think I have understood your concern. I will suggest you the best possible treatment options.
1 ) First of all do not panic.
2 ) You are absolutely right about the chance of getting pregnant as pre ejaculation secretion does contain sperms. Also , you have rightly taken high dose
progesterone tablets within 24 hours of unprotected sex act.
3 ) After use of such tablets as emergency
contraceptive, you can experience erratic bleeding as a withdrawal. It can be early or late, heavy or scanty.
4 ) If you have had bleeding on 7th January, then you need not worry. It can be your menses. But if you have any doubts about it, please get mornings first sample of urine tested for
pregnancy, if you still have doubts then blood
beta HCG test and USG will be of help.
I hope this answer helps you.
Thanks.
Dr. Purushottam Neurgaonkar.
