Last 년 when I found outbi had hashimotos, those symptoms happened, but my endocronologist just changed my pill schedule, so thats probably why I feel that way. my mom thinks its not cause of that, she thinks its my perios but I wake up to no blood. anyways im getting off track.. But my 질문 is, do 당신 guys who are 읽기 this think that the stomach ache/dizziness means my period is coming, 또는 is it something different. Thank 당신 if 당신 help(:
