Any responses are greatly appreciated

Last year when TTC I took clomid. One cycle of 50 mg didn't ovulate and two cycles of 100 and ovulated on both. Well it's been six months and we are TTC again. I took clomid 100 mg. I've gotten a positive ovulation test and I had pain the day I got the positive opk. But I haven't had the pain I had before when I did ovulate. I knew for sure I was ovulating with the other cycles. Could I not have ovulated this time? Or is it possible maybe it's not as painful because I'm used to it? Ugh stressed as heck right now.
