Me And My Boyfriend Are Sexually Active And Trying To

Me and my boyfriend are sexually active and trying to conceive. I have had unprotected sex, where he ejaculates in me almost once a week in August, and throughout July. I have had Naseua, bloating, tender breast and what I think might be a Montgomery Turbecles on my right breats. I never experience these symptoms before a period, although I know some women do. Yesterday, I was due to get my period, and I had some brown discharge in the morning, only when I wiped and then later got some bright red bleeding. The bleeding is only apparent if I wipe, and there is nothing on my pad. Today the blood was a little heavier, more red, but there is nothing on my pad.
I am sad that I might not be pregnant, and I am afraid to take a test because I don't want it to say I am not pregnant.
