Hi, I'm a mommy of 2, I went on BC 8 months ago, here is my issue I had my period March 9th, on March 25th I had intercourse, then on March 31st I had to pee, when I wiped I had some red spotting on the toilet paper, after that NOTHING more, from that day on I have had cramping, headaches on and off, super dry mouth and throat when I wake up in the morning, and super tired, bubble guts, I just wake up and it feels like I haven't slept, I feel like something comes out I run to the bathroom and think it's AF but nope it's little discharge . . So anyways I took a test (Walmart brand) last week and a first response today NEGATIVE! what's going on?? Can anyone help?
