Hi, my last period was on 17th of July and I had sex with my boyfriend on 28th of July at approximately 10pm-11pm. Took Escapelle on the next day at 1pm and experienced those undesirable side effects such as fatigue, dizziness, but those only last for a day. And as I thought my period is coming soon, which was happened on last Friday, but it turns out I have lower abdominal cramping, but the cramps are fading. I also have sore nipples which it sustain for 5days and it's worsening. been 2 weeks now and my period has yet to come, took pregnancy test on last Saturday night and yesterday morning and it show negative result. So is it normal to feel sore nipples and slight cramp after a week of taking the pill? And is it possible for me to get pregnant?
