I took an ovulation test 2 days after my period & it said I was ovulating so me & the hubby baby danced that night. It's been about 7-8 days since then..I'm now having bright red/brown spotting, lower abdominal cramps, diarrhea in the morning & im more tired. Can I be having early pregnancy symptoms already? & what's some of the early symptoms you had before finding out u were pregnant?
