Been ttc for 5 months now after 3 miscarriages

Destiny • I`m destiny, my so and I have had two miscarriages and then 1 chemical pregnancy/mc I have a beautiful healthy 4.5year old. My wife and I are trying for baby number 2.
3.5 yrs ago was our last miscarriage, our marriage fell apart, we had to be separate for a while, but we worked through it, and gave ourselves time to heal and work on us. Now we have been ttc for 5 months with no luck yet. Every time we tried before I would get pregnant the same month so I never had to do the waiting part :-( I hope something isn't wrong now and my eggs have decided I'm to old lol (I'll be 26 this Friday). I'm thinking about consulting with a ob about it and having blood work drawn and everything I heard a simple hormone imbalance can be an easy fix but make ttc very hard. I know 5 months don't seem like a long time, but to me it is. Especially with how many failed pregnancies I have had. Anyone have any input? Or going through something similar?
