Hi, I am a 25 year old female, healthy weight, exercise everyday. My husband and I are planning to conceive, so we have stopped all methods of BC. Last cycle, I had spotting for few days then normal period for 1.5 days and spotting again for couple of days. I figured it was my usual period as hpt was negative. But a week after that, I have been experiencing severe nausea for 2 weeks, headaches, frequent urination and fatigue. While growing up around 15 yr old, I had thyroid problem(damage to the gland) which was managed and went away pretty quickly. Could it be hypothyroidism, as all my aunts and grandmother have the same? Thanks in advance.
