so my son is 20 month now and we have been ttc for about 4 months now. my first son was easy! we went off birth control and a month later I was pregnant! I never went back on birth control after I had my son and we never really used any other methods to not get pregnant. we have just been going with the flow. we weren't having sex super often in the beginning just because we were getting used to a newborn. the last 3 to 4 month though we have been trying very hard! it was so easy the first time around it's starting to get really frustrating that it just isn't happening yet this time around. would it be to early to set up a doc appointment to make sure there is nothing else going on as far as fertility?
