My period ended July 29th. I had unprotected sex July 31st and he didn’t pull out in time. Less or an hour later I took plan B. I am also over weight and I just read that it’s less effective?? Yesterday I had bad diarrhea not painful or anything just random. Thought maybe I ate something bad. Today I started working out because I need to lose weight haha. After my workout I went to the restroom and I noticed some spotting. What could it be?? Implantation or just my starting to workout?? Also I’m 6 days from ovulation.
