So I started BCP almost 3 weeks ago but had unprotected sex in the first week of starting the pill towards the end of my last cycle. This week is period week while taking the placebo pills. Today I'm assuming its my period starting but its so weird. Its darkish brown and only a little bit. I have NO pain at all. Usually my periods are rough on the first day and get better as the days pass. How the heck am I suppose to know if its my period starting or implantation occuring? 🤔
