Hi, I have a unique hypothyroidism condition where I was not born with one. I am female age 21 and I take levothyroxin 175 MG everyday to help my hypothyroidism. My question is. I have all the symptoms of being pregnant, very sore heavy breasts and nipples larger too, very tired during the day, very awake at night, I just feel off, nausea, dizzy, weird appetite, lower back cramps, stomach cramps, feet really hurt. All that jazz. Yet both pregnanCy tests I have taken were negative. I was wondering if my hypothyroidism and weird hormone levels can throw my hcg levels out of wacky for the tests?
