I'm cramping really bad but not like period cramps. Earlier I was taking out a old king size mattress , deep freezer microwave and other stuff for the bulky pick up and I felt so off balance it was weird.my boobs feel tingly to. I took my bbt this morning and it was 97.60 and the opk was still very positive. On the 14th -18 I had very watery light brown cm when I wiped could that have been my period? Because according to my app I got a positive on opk on CD 10 Is that normal?
