My last period was on Aug 22 and since getting my period back after having my son in March ‘17 it’s like clock work. According to the app I ovulated Aug 31st to Sept 6th. I goofed the week of August 27th and did not take my pill and had sex on Aug 31st and Sept 1st. I had what I think may have been implantion bleeding from Sept 7th to Sept 11th. It was light spotting and not heavy like I usually experience. I took a pregnancy test today since I expect my period Wednesday Sept 19th but normally I get my period a day or two before what it suggests on the app. It was negative but still worried I could be pregnant. Obviously I know I still need to wait and see if my period shows up, but it’s so hard not to think about it!
