TTC with 5-6cm Fibroids

Zara • Trying to conviece first baby after 2 MC`s, June & August.
Hi ladies
I was just wondering wherever it's possible to have trouble getting pregnant with 5-6cm fibroids? 
Would it be best to ask to remove the fibroids and maybe that may increase my chances of conceiving. 
I've had 2 previous pregnancies but both ended in a miscarriage. 
My last miscarriage was August 2014 and since then we haven't had any lucks yet and I don't know wherever it's due to the fibroids or not. 
Has anyone had fibroids removed and managed to get pregnant?  
Oh and I think the fibroids are in the outer lining of my uterus 
Thanks in advance
