Hi Pearshaker,

I had the same pain after DTD the other night, it lasted for 3 days, started as curl-in-a-ball pain, then just a painful ache in between my hips. My who pelvic area was slightly swollen too, and I couldn't even lie on my belly.
There's a possibility that for me it could have been Ovulation, as my temps & chart are being very tardy and won't tell me if I've ovulated yet lol.

Anyway, technically, from the leaflets that I've read that come with the pill packets, the pill doesn't actually stop ovulation, it may delay it (if you have a short cycle) or shorten the time between AF finishing and O (if you have a long cycle) but the main thing that the pill does is change the lining of the uterus to make it hostile to the ovum & not an easy place to burrow into.

Also, the first 5 of my 7 pregnancies (6 are now angel babies) were joint pill & condom babies lol very scary when you're trying to be careful & NOT get pregnant and you do.
