22 years young ive been ttc for 4 years

I have a 7 year old 

I feel as if im infertile and will never give my daughter any siblings and some time it makes me wonder. How could i get married to my fiance so soon without knowing.

I still have my cycle and only 1 abortion when she was 4. Is this punishment from God :( sometimes i feel less of a woman because my body dont function enough for a birth. I feel something spiritually is wrong here. 

Im just 22 years young.

I eat healthy and exercise

I even turned into a vegetarian 

....I've had leap last year. What's going on!! My daughter and i want to know :(
