Next step advicešŸ˜

My boyfriend just told me yesterday that he doesnā€™t necessarily want to TRY to have a baby, not gonna buy fertility tests and schedule sex sessions or anything like that, but to stop preventing it if that makes sense? Basically TMI-he wants to start finishing in mešŸ˜‚ So I just want to know what steps I should take to make sure I am even able to have kids? I have fairly regular periods, give or take a few days in the cycle. Iā€™ve never been to a OB or even had any appointments in that area except for a yeast infection a few years ago. Who do I see? What do I say? How do I go about it? Thank you so much in advance!
