Spotting (repost)

Leah

This is supposed to be my ovulation window but I’ve been spotting for a week which is unusual for me. Nothing heavy, just some pink when I wipe. My feel like poop, body is sore, bloated, sore boobs, sore back. This can’t be my period could it? My period is usually very very heavy. It’s not due until March 4th. Ever since I had my iud removed 6 months ago my cycle has been long, almost 40 days. I wonder if this is my body going back to “normal”? Opk strips negative and same with pregnancy tests. Anyone have similar and get a positive test later on?
