Hello! I was 5 days late on my period and on the fifth day I experienced light spotting of old blood. For the past week, I have been experiencing nausea, constipation, moodiness, extreme fatigue, back pain, frequent urination, and bloating. I took three OTC pregnancy test (3, 5, and 7 days after my late period). I took a doctor's office pregnancy test today and it was negative. I am 28 and have been on 5mg of levothyroxine for the past three years. My TSH, T3, and T4 levels were normal in January. How could my hypothyroidism impact the pregnancy results?
