Ready for the third but low FSH

So my husband and i talked and we want one more kiddo! Only thing is when i went to my dr for normal blood work.i made her test my hormones ans discovered that my FSH is low she made me redo the test2 months later and it was still low. So she sent in a referral for endocrinologist i go in January. I know weve struggled getting pregnant in the past weve had 8 total pregnancies with only 2 babies with us. Im wondering if anyone else has gotten pregnant with a low fsh? Should i take anything to hopefully help?
