Sorry for the repetitive posting but

I'm really looking for an answer.

My DH and I were trying to BD and it was REALLY difficult getting him in because I was extremely tight (and not because I wasn't aroused)

I'm wondering if anyone has experienced this in early pregnancy? I'm waiting until morning to take a hpt but my period is late and I have a few other symptoms. Am I reading too much into this or is this something others have experienced?
