Hi I'm new to this, but could use some hope in what seems a hopeless case.

I'm a newlywed (married in April), I've since miscarried twice (once in June again in September). All of my life. I've been told that having children will be hard for me, and until June I didn't think much of it. I have endometrious and have a lot of scar tissue, my Dr.s have always said that if I didn't carry full term before age 23, I most likely wouldn't be able to ( scar tissue can block my tubes, scar tissue on other organs make carrying a child full term unsafe).
The two times I've miscarried were unplanned pregnancies, but were very wanted. My husband is of the opinion that we should not be ttc just yet, and is unwilling to even think about making a plan. After the miscarriages I realized just how much I want children and that I'm ready to be a parent.
My husband doesn't even know about the second miscarriage, he knows the Dr. was almost positive I was but the blood test didn't have enough hormone in it. I didn't have the Heart to tell him every thing (he was so heart broken the first time. It really hurt our marriage, because we were both really hurt by what happened ).
I've become obsessed WITH POAS and keep thinking that it happened twice surely it can happen again. I'm feeling hopeless because my husband won't even talk about planning, I'm afraid I'll hit my time limit and never have children of my own.
