Possible miscarriages?

Ok so me and my husband have been ttc for about 7 months. We stopped ttc for two months because we wanted to make sure we were ready we had some doubts and things but now are back on track. My question is about my , whenever we are ttc that month my will hurt one or two days after ovulation really bad too and stay painful until I get my period which is usually right on time. However I noticed that the two months we were not trying they wouldnt hurt until almost the day before I got my period could this be a sign that I am pregnant and miscarrying early? Or maybe just a fluctuation of hormones and completely coincidental.
