In September I got my period twice, the normal one was Sept 6-11 (this is the one that I was expecting, it came when it was due) nothing was strange about it at all. Then on Sept 20th I woke up with my underwear covered in brown blood. Sometimes I get brown blood right after my period but I've never had it mid cycle like this. I would have just thought I was shedding old blood but there was some red blood mixed in too when I wiped (so I knew I was actively bleeding again). This continued for 6 more days and then stopped on the 26th. It wasnt nearly as heavy as my normal period but it was enough for me to need to wear a light tampon the entire time and it was both brown blood and red blood most of the time. The last 2 or 3 days that I had it, it was super light and was 100% brown blood only but I still wore a tampon so I didn't ruin my underwear. I had period cramps for both periods last month so I know the 2nd one wasn't breakthrough bleeding. Also my "second period" couldn't have been implantation bleeding either because it was way too early in my cycle plus I would've tested positive on a pregnancy test a few days after that, now it's been 3 weeks since it happened and I'm still testing negative.

I've been rediculously tired (like..so tired that I accidently fell asleep at work for 3 hours) and as of about 8 days ago my body odor has *completely* changed to a much stronger odor with a different scent that I've never had before. I am 100% sure that I took my pill every day at the exact same time every day between my 1st and 2nd periods in September. I don't believe I missed any pills after my 2nd period ended but I have multiple pill packs scattered around my car/purse/bedroom so I can't check what day I'm on because I use all of them. I know I did take 2 pills a few hours late but that wasn't until after the double period thing was over so I know that wasn't the cause of it.

If I go off the date of my first period then I should have gotten my period this month on October 4th but I didn't get it yet. This is the one I think I should be going off of because it was my "scheduled" period that I was expecting and it was red blood the whole time like my normal periods. If I go off the weird second period then Im due for my next period on October 18th (5 days from now) but since that one was mostly old blood the whole time and was a very light flow I don't think that was an actual period, I think it was some weird mid cycle bleeding. So basically I don't know if I'm late this month or not because I don't know which "period" I should be using to calculate my next cycle. My boyfriend finishes inside me every time we have sex (once or twice a week) but I took another pregnancy test yesterday and it was still negative. Does anyone have any idea what's going on?
