I had sex with my bf when he came back around the end of March (which is the normal time I get my period) and right after, I had my period. Throughout April, we abstained and I was supposed to get my period around last week, but instead I got this very light brown/pink discharge for 2 days (Friday & Saturday) then it went away and now my CM is back to normal. I didnt experience any cramping or anything like I normally would when I get my period. I took a test on the 23rd, Thursday but it was negative (then again, the test I took I think isnt as accurate as EPT)

Could I be pregnant?
