My period was due on the 8th, on the 9th I got some red blood around 3 pm when I wiped, so put in a tampon , assuming my period had started. Went to work and didn t have another tampon, so I just took that one out. After that I only had pink when I wiped. This continued to get lighter. Last night it pretty much stopped and this morning after my bf and I had intercourse there was a small, small amount of brown, then I stopped spotting all together. I took a pregnancy test and it came up negative. Any suggestions? (my last actual period was july 11th and we had intercourse July 21st, when I should have ovulated).
