I've been feeling like I am pregnant(sore boobs, increased appetite, frequent urination
, back pain, sleepy all the time, etc), and my period is three days late already, but all the tests I've taken are negative. I just got off the pill right before my last cycle began, so I really don't even know whether I ovulated this month. On top of everything else, I have hypothyroidism, so now I'm kind of afraid that that is why my period hasn't come. I'm worried and frustrated.
