So I was supposed to be ovulating Feb 4-11, but when I took my opk the first couple of days it came out negative. my hubby and I BD 3 times during my glow ovulation period prediction. Yesterday I began to have some cramping, like period cramps. Also, today I'm not supposed to be ovulating and the cramps were worse today. I'm not sure if this happens with ovulation, or if this could mean I may be prego. Please let me know based on your experience what it has meant.
