TTC with Thyroid problems

I just wanted to see if there were any ladies out there with Thyroid issues. Ive had hypothyroidism since I was about 22 (26 now). I have one son already he's 3 and we're TTC #2. Because of my thyroid this is month #2 with no period but negative pg tests. with my son I got pregnant in December of 2013 but hadn't had a period since October 2013... I just wanted to see if there was anyone in the same boat as me. I can't even get excited about missed periods cuz of this damn disease.
