2 years. 2 pregnancies. No Success.. HELP!!

So in September of 2014 I found out I was 4 weeks pregnant, and ended up having a miscarriage. I took a break from TTC, do to the physical toll it took on my body and emotional toll on our hearts (fiance and I).

We began to try again in February of 2015 I ended up pregnant just after 5 weeks TTC. I ended up having a second miscarriage @7 weeks...

Since then we have stopped trying, however are not taking any precautionary actions to prevent pregnancy.

My mom and grandmother BOTH had to get hysterectomy by the age of 26..

I'm afraid that if we do not conceive a baby soon I will lose that chance..

Ive been trying to conceive on my own before contacting a fertility.

any advice?
