Does anyone here have a hypoactive thyroid? I just took my clearblue digit ovulation test and I got a blinking smiley face. I was super excited but then realized I haven't taken my thyroid meds (synthroid) in about 4 days. I know your estrogen and thyroid take major roles in each other and I'm wondering if I got my blinking smiley because my levels possibly being screwed up from not taking my synthroid or if I really am fertile. Has anyone had this problem before or have in insight? Or am I just over thinking?
