Hi there, I have understood your concern. I will suggest you the best possible treatment options.
1 ) First of all do not panic.
2 ) As you might be aware that in a woman with regular cycles day 10 to 20 of the cycle is the most fertile period of cycle. If you have unprotected sex act in the fertile period of cycle, then you stand chance to get pregnant.
3 ) Also, you have taken the
emergency contraceptive pill, within 24 to 72 hours of unprotected sex act, you need not worry about the
pregnancy. Also, your unprotected sex act was before day 10 of the cycle, your chance of getting pregnant are almost nil.
4 ) Your bleeding can be related to high doses of hormone
progesterone in these pills.
I will suggest you to wait till your expected date of the cycle.
If you happen to cross your dates or start getting some pregnancy like symptoms, then you can get morning's first sample of urine tested for pregnancy. In case of doubt blood
beta HCG test and USG will be of help.
I hope this answer helps you.
Thanks.
Dr. Purushottam Neurgaonkar.
