Am i crazy?

Sooo we’ve been TTC and this is the first month. Today I’m ovulating and we did it yesterday to,however yesterday it felt like i was on my period,no blood or any discharge just a bit crampy and my uterus was feeling weird. And i was pooping a bit. I Normally don’t get this when i ovulate just normal PMS symptoms eventually i did feel the twinge by my ovary last week to and i took a pregnancy test yesterday but it’s negative also we’ve been baby dancing every day since my period ended..what do you think this means?
