Fertility

I don't really have anyone around me that I can talk to about this because none of my friends or family really understand my situation... I have Endometriosis. As you can imagine, infertility is common. I am beside myself most months. My boyfriend and I have been having unprotected sex for over 6 years, and we've honestly never been careful in hopes that maybe someday it would just happen.. I do have insurance but it is limited.. Without being married to him and having his wonderful insurance I cannot look any further into this for now.. But I can't help but get my hopes up every month only to be shot down. Can anyone level with me ? My heart is crushed.. 😔
