### input:
HiI am a 23 year old female. I have regular periods. Avg cycle 28-29 days. I had a regular cycle from Aug 4-8 (5 days). My bf and I had an unprotected encounter on Aug 10 (day 7 of my cycle) and I had an I-pill (emergency contraceptive) within an hour. The next day, i.e. Aug 11 (day 8 of cycle) the condom broke. I didnt want to pop a pill again so didnt. I had mild bleeding that started on Aug 15 (day 12 of cycle) at night. It lasted until today, i.e. Aug 18 (day 15 of cycle). Unfortunately, the condom broke today again (this literally angers me). Had to take in an Unwanted 72 (emergency contraceptive).My question is:What exactly was the bleeding on Aug 15 (day 12 of my cycle)? Was it ovulation bleeding (I never got that ever in life), effect of the pill (withdrawal bleeding) or implantation bleeding (so wishing it isnt this one)? The bleeding was scanty as compared to my regular cycle but enough to make me wear a single pad all day (not soaking it but still not little enough for Undergarment to hold).When should I be expecting my next period? My regular due date, i.e. Sept 2-3 or when?Could I be pregnant?Please answer ASAP! I am worried here.P.S. I have made a promise to myself. No more ECs. Enough is Enough. A dual condom or whatever will be tried but this breaking is so making me mad everytime.

Hi, Thanks for your query. Here are your answers -1. The bleeding on August 15th was the effect of the pill (with Chat Doctor. 2. ECS notoriously alter the normal course of the menstrual cycle, your normal period next time around could be a week or ten days earlier or later than expected. There is no way to predict when it would be.3. Well, EC s are over 95 % effective in preventing a pregnancy when taken within 24 hours, so the chances of pregnancy are quite low. You would know only next month, when and if you skip a period, and take a test.4. Yes, ECS taken so often will wreak havoc on your cycle and on your system. Take care.
