You should go out & buy ovulation test. Iv been ttc for 5 month. Durin ovulation i get cramps & cervical mucus. Can also tell with feelin ur cervix it will go really high, soft and open. Also my nipples hurt day after ovulation. Tht was how i estimated wen id ovulated. Last 2 month i bought ovulation test and got my first positive both times on CD 13 than CD 14. Ovulate on CD 14. Im still not pregnant yet tho having trouble with spotting right after ovulation think its affecting me getting pregnant. Good luck!
Yes increase in body temp cervical mucus cramps
