Recurring miscarriage and fertility clinics

I just had a follow up with my obgyn after a second miscarriage. She referred me to two places to choose from: a recurring miscarriage clinic and a fertility clinic that does IVF. She suggested the latter may be best so that when I do become pregnant again, they have the capacity to do weekly appointments to closely monitor the pregnancy. To be clear, I’m not looking for IVF, but rather some insight into what may be causing my miscarriages (if anything) and to be closely monitored for a future pregnancy. Anyway, I called both and neither take my insurance. I’m wondering if anyone has similar experiences and if it’s worth paying for this out of pocket. My fear is that I would go to the IVF clinic that she recommended and would end up spending a whole lot of money for something that is just precautionary, or that I spend $300 for the initial consultation only to realize what they’re offering isn’t what I actually need. I’m getting extremely frustrated navigating the health care system which is compounding my anxiety about having a healthy pregnancy. I appreciate any insight.
