Well my period usually lasts for 7 days while not on any birth control. I had taken out my nexplanon and 2 weeks later my period started and lasted for as long as I thought it would ( 7 days ). I was due for my next period on the 17th of this month but I got it the 14th, no biggie. But it only lasted 3 1/2 days. Throughout the whole time, maybe a week before, I was soo sick to my stomach, had pain in my uterus, and just haven't been feeling like myself. I am also ttc. I just don't know what to think... Please help.
