TMI ALERT! Brown blood after masturbating?

[Amfahner]

I'm in a super awkward situation. Me and my boyfriend aren't trying to conceive, but we're definitely not careful, and haven't really been for the past couple years. He doesn't necessarily want a baby right now, but this month I've been having lots of symptoms and I've got myself really worked up about it, and I'm going to be really disappointed if I'm not pregnant. He says what happens happens, and I have baby fever like crazy. Anyway, af is due Saturday, July 12, planning on testing then. I'm hoping for some insight here, my symptoms as of today are: peeing every hour or so, super tired, can't get comfortable anywhere, bloated, gassy, headaches (not saying much because I always have tension headaches) and out of nowhere, a two day freaking nose bleed! I've never had a nose bleed like this in my life! Bloody booger in winter sometimes, but I live in a very humid climate and it's the middle of summer! Wth? Anyway, (TMI WARNING) I masturbated, and I had some brown blood when I wiped. I actually cried because I thought I was gonna start my period. Nothing yet, but I'm super heart broken. Just wondering if this has happened to anybody else?
