ok so I have irregular periods so I'm assuming my ovulation is off too. anyways I'm trying to keep track of everything now to see if their is some sort of pattern or least be able to tell what up by my body. So my period was about 3-4 days beginning of this month (july) my husband and I do the pull out method. (we figure if we get pregnant then so be it if not then so be it, I usually use this app to guess my period and possible fertility window so to avoid pregnancy) sex on July 9th sex on July 16th. now after sex I go potty and clean up if we don't take a shower right away! nothing unusual, go potty few more times and even around 3pm nothing unusual.. July 17th comes around around 11am I go potty and wipe and it's brownish discharge.... I wipe again it's slight brownish but mostly a egg white mucus (cm?) ... why would it be brownish? could this be early pregnancy? glow says my next period isn't til around Aug 5th.... when I see blood out of the normal and sleepy and upset stomach and sex has been near I always take a test! so yes today I took a test which was negative (figured as much bc I know it could be too early since period isn't til beginning next month) so what could this be?
