Infertility specialist appointment

I have mixed feelings about the appointment. Basically, the doctor went straight to a plan of actions: 1. test progesterone 2. get a endometrial biopsy (check uterus lining) then next cycle 3. get a HSG test, where they pump ink into your uterus to see the structure of it.

All this would take about 2 cycles, in which you can not become pregnant. There's a 50/50 chance they will find something wrong, or nothing at all. So second plan of action is to check for genetic problems, which could take another cycle. In short, I can take about 3 months of testing to have a 50/50 chance of find something wrong and have 50% chance of being able to fix it, or not at all... and the flip side is that we may not find a single thing wrong and those two miscarriages occurred by chance - or "bad luck" as he put it. If that is the case, then I would have wasted 3 months of testing for nothing.

On the flip side, we could get pregnant this cycle, and either carry full term (no time loss), or have another miscarriage, wait around for at most 3 months before we find out the pregnancy is not viable... then take another 2 months for the miscarriage to finish, and end up right back where we are right now. Except then it's certain that we need medical intervention. But then I would have lost 5 months... and another baby. And would need another 3 months of testing before we could try again. That's 8 months of time lost. But I guess by that time, it doesn't really matter because obviously I have a very severe reproductive problem.

I'm not sure what to do. Try again and hope that third time's the charm, or have another miscarriage and get really angry at myself for consciously choosing not to test and correct any reproductive problems and killing another baby because of my actions.
