I made an appointment to see my doc and discuss ttc and he also gave me a health check - he didnt take bloods though as i had had them done for another condition previously.
I am currently getting depo out of my system and the doctor did a blood test to check and see if i was producing the right hormones - which i am not and so i need to see a gyne! I would go to the appointment and discuss it with your doctor, they give you a load of info sheets too so its worth it.
Good luck and welcome to the ttc board
