Hi, I'm 18 and I have Hypothyroidism. I've been taking medication for it since I was born but in December and January I basically stopped taking it. I restarted taking the meds in February and I know that it takes about 6 weeks for my levels to get back to normal. This week would mark week 7 and while I missed my period last month I thought it was because of my thyroid levels. The thing that worries me is that I have yet to have one this month and I usually never miss a period and always know when to expect it. Me and my boyfriend are having unprotected sex but he has never finished inside of me. I was the same way with my ex-boyfriend and we never had a problem so I wasn't worried when me and the guy I'm dating now got intimate. I may just be over reacting and stressing myself out but I'm worried because everything I've read said I could either be pregnant or have secondary amenorrhoea? I have been unable to take a pregnancy test due to the fact my parents don't let me out of the house much and would kill me if they found out I was pregnant. I'm very worried and don't know what to do! help please!
