Hello puppyknuckles.  While I don't know the answers to your question I found this on the MacMillan Cancer Support website which may be a good starting point for you.  Best wishes.  Annie

Thnak you Annie, this is reassuring. I am thinking about going for tests when i come off the pill. 

Hi I know some chemotherapy drugs can possibly cause issues with fetility (not quite sure which ones specificlly) but there are people that had childhood cancer that go on to have kids. there was an episode one one born every minuite where someone had cancer as a child and was having her first baby. all went well . i think the pregnancy was slightly high risk because of the possible strain on heart but she was ok and if you look up stories of childhood cancer surivors some of them have kids. the best thing is to try and if you have issues conciveing then see someone about it. best of luck to you x
