Recently my husband and I started trying to get pregnant around the same time my endo increased my thyroid dosage from 137 to 175. My period has always been pretty regular 25 day cycles but now I'm 2 days late I also thought I experienced very minor implanantiin symptoms that went away but the pregnancy tests have been negative. I don't know if I'm pregnant or if my period is late because of the increased dosage. I have never missed a period before. I travel for work and this shift in timing is throwing everything off. I just want something to happen at this point don't care. I'd love it if I were pregnant but I doubt that's the case I just don't feel any different.
