Need some help

I got my iud taken out the beginning of February got my period right away. Then got my period the end of February, we had unprotected sex while ovulating as my Gyno said we can start trying after two cycles. Now I’m two days late for af and I’m having all these symptoms but all negative test. Is it just my hormones trying to get back to normal or what? 😩😩 it’s driving me crazy

I added this for it to make more sense I’m new to this 😂
