I had unprotected sex. 36 hours after I took levonorgestrel as recommended. 3 days later, my period was due and came on time. 4 weeks later it also came right on time. I’m 25 and this was my first time taking any form of birth control/hormonal pill. 7 weeks later I am bloated and heavier than before. Could this be a side affect of it? My weight is always the same and nothing in my life has changed to alter it, except I took a pill 7 weeks ago.
