I'm trying to conceive & am on my first dose of clomid (clomiphene) 50mg, on the 21st day of my cycle my partner and i had sex and it hurt a lot, why could this be?

Deep or shallow?: Shallow intercourse or pain on entry may indicate an "unreadinss" for intercourse with poor lubrication. Deep pain may be a sign of endometriosis or enlarged ovaries from the clomid (clomiphene). Please talk to the md who rx'd the clomid (clomiphene).

Vaginal pain clomid (clomiphene): Clomid (clomiphene) blocks estrogen receptors which may cause decreased cervical mucus or vaginal dryness. Alternatively, you may have an ovarian cyst from the Clomid (clomiphene) that may cause pain.
