so i've been on depo for a year & 8 months and during this time i've only gotten my period like 3 times. so i took a pregnancy test about a couple days ago it said negative. but i took it cause i've been feeling nauseous dizzy and weird symptoms for like 2 weeks. after i saw negative i was relieved maybe i was stressing myself out and giving myself these symptoms. but today couple days after the test, still nauseous, a tiny bit of cramps, and when i wipe the second time i see this on my toilet paper. is this from being pregnant or a period actually coming? when i wipe the first time i don't see this really it's just alittle dark yellowish light brown almost
