I know this is dumb, but how long do premenstrual symptoms normally last? I just can't remember... it's just been so long since I've had a real period; when I induce my period with progesterone I'm crampy for maybe 2-3 days. I might be pregnant and have been having cramping for the last 6 days... I'd think if I were going to get my period, it'd be here by now (I'm on CD 31, ovulated anywhere from 12-19, I think closer to 19, no +HPT yet but no period either). The cramping today is the worst it's been, on par with what I usually feel the first day of my period. I am spotting very lightly, have been since Sunday... I thought because I'm constipated (sensitive cervix), mostly brownish , but it doesn't seem like my period is starting and I spotted a lot with my first pregnancy.
