i'm trying to conceive. Last month I felt pregnant symptoms like bloating, relieving lot of gas, indigestion, light-headed, slight headache, but got my period on the actual period date. The period only lasted for 1.5 days, which is usually 5 days. My TSH was 8.13 during august, Took thyrox-50 and now 3.22. after periods also i felt the pregnancy symptoms. So tested for beta HCG and came 1.2 (negative). Checked for PCOs and none found. What to know why i got those symptoms. Am i normal?
