Bailee
Okay ladies, I've had my period for 13 days straight and so my doctor told me to go on birth control to stop the bleeding and regulate my period, well I've got caught up in everything today I forgot to take my pill today, I've only been on them for 3 days and today I missed taking the pill. Well I take it every day at 7:21pm for the passed 3 days and today I dident take it. Well it's only like 3 hours ago when I should of took it and I just used the bathroom and I wiped and there was some pink blood that looks like implantation on the toiet paper.. Am I gonna get my period back? Or what should I do??
