Feeling frustrated TTC

I feel so frustrated TTC. Last year I had 2 miscarriages. At that time we were not trying to get pregnant but we were happy when we concieved (figured out from ovulate strips, I actually ovulate about 3 days earlier than the app said, when why I got pregnant). After my 2nd MC I went to a specialist and found out I had uncontrolled hypothyroidism. After starting the medicine and getting my levels back in range (took 2 months) we began TTC again. Now I feel frustrated because It was not yet happened (4 months later). I feel like when we weren't trying I got pregnant so easily! My husband still wants to try. Deep down I do too, but I'm tired of being disappointed.
