so, me and my boyfriend are sexually active. and I got a positive ovulation test on the 16th or 17th. 6 or so days after that I got one little drop of pink blood. 2 days after it looked like my cm was mixed with the faintest pink color. starting yesterday I had super painful cramps and a sensation in my stomach that would tighten and feel like it needed to expand. and I felt Nashua all day yesterday. starting today I feel so bloated . my period isn't due for 4 days. what does this sound like to you? did this happen to u ?
