Pain... Tmi question

I don't often post about this stuff but feeling a little concerned. 
Hubby and I have been Ttc for about a year now. Have started clomid, on our second cycle of it (100 mg). I just started the fertile window last night. 
When BD'ing last night, I was in a lot of pain, feeling like he was too "deep". Now, the same area hurts when moving around. Sharp stabbing pains. 
Anyone have similar pains after sex ? And know what/why? 
TIA!
