Ovulation!

So here is my charting this cycle. I know it's not as dark or darker but I have PCOS and I've been told it's hard to get the lines as dark or darker. I've had cramping ALL day today. Could I be starting to ovulate? The last two test are from today the am & the mid day (now). I don't wanna miss it and keep waiting but my husband is getting tired of monitoring sex haha.
