TTC Kidney Transplant

Jo
I have been trying to conceive since November 2013 so 10 months now 
​My boyfriend had a kidney transplant nearly 3 years ago so is on medication for the rest of his life which I know causes problems with his sperm etc
​but my doctor said it could still happen which I do know because I know someone who has also had a kidney transplant and he has 2 children I'm just finding it hard to stay positive every little pain or ache or my boobs get huge and I get excited but it's just turns out it's period symptoms and then I feel miserable when my period turns up ?
​I know he would be an amazing dad and I'd love one day to be a mum 
​Is anyone on here in the same situation with a success story or just someone with some advice I'd love to hear from you I'm struggling at the minute and getting worried I might never be a mother ?
