The cramping is very like the pressure of the follicle and is perfectly normal. Not everyone feels this, but when you're actively TTC and know when you ovulate, then that increases the chance of you feeling it! A fully-formed folly is pretty big and can actually be felt by a trained hand through the body, so it's no wonder you can feel it rupture or feel the pressure of it growing! You can have ovulation pains before, during, and even after ovulation...once you figure out where your pains fall, and if they are consistent month after month, you could actually find out when you O just through O pains! I was TTC for quite some time, so I became very accustomed to 'listening to my body' and finding my O days, even when I had stopped charting BBT.
