Had unprotected sex 2 days ago, 4 hrs later had one ipill on same day. She was on 4th day of period with negligible bleeding. As per after-effects of contraceptive, we were expecting bleeding in next few days but till date, she did not feel anything unusual - period is over, no pain or uneasiness due to contraceptive pill. Does it sound fine or will the effect be seen later ? Just wanted to understand as this is our first time with contraceptive.
