So let me start off by saying I've never had cramping during my cycle except for the day my period comes. About three days ago I had a couple pretty decent cramps that would last for about five minutes on my right side. According to glow my fertile week began Monday and ends Sunday. Got a LH surge on Monday tho...So I'm wondering if it's just maybe a first time ovulation cramp or maybe possible implantation? My boobs are also sore but not to the point that I can't even touch them.
