Recently I ve felt very tired, sore, nauseous, very bloated and have had bad headaches. My stomach movement kinda feels like it did when I was pregnant but I just had my period and before that I took a test and it was negative. I noticed my tongue has a yellowish layer of thick mucus towards the back, that s been there for several months . My weight fluctuates a lot before, during and after my period. I m on 88 mcg of synthroid and started an antidepressant a few months ago after my father had a stroke. Do I need to get blood work done? See my OBGYN ?
