I started the pill about 6 weeks ago and am now on my second pack. But, since I started sex has been extremely painful for the first minute or so... It's the entrance that hurts so once it's been stretched a bit it goes away. I've got a gum appointment this friday and have already got a negative result for chlamydia. I'm not sure if it's a coinsidence that sex started hurting once i'd started the pill or whether it is related as towards the end of the pack it started to ease of but now a week into my other pack it's just as painful as it was last month. Also it smelt or the first week too just as it does now... Any ideas on what my problem is ?

Thanks :)
