Hi, may I answer your health queries right now ?  Please type your query here...Hi i had been having symptoms of pregnancy 3 weeks ago, I took a test and it was negative. Just 4 days ago i started cramping really bad and i went to check and i was bleeding and i figured i just started my period. As the pain kept getting worse i started notecing i was passing very dark thick blood clots. As soon as my period came my nipples that were hurting before are not hurting now, but i do still have nause and have also developed diarrhea, headaches, gas, and sometime fever if pain gets really bad. I have a history of not getting my period for months at a time, and was diagnosed with hyperthyroidism. What could i have? Did i miscarrie even thought pregnancy test was negative? I have been trying to get pregnant for 3 years now and am not taking any medication for my thyroid. I hope all that info will help you help me. What can i do about this very painful cramping?

### output:

Hello dear, I understand your concern. In my opinion the hyperthyroidism might be the cause for heavy bleeding and irregular periods. The irregular periods in turn lead to infertility. The thyroid abnormalities are one of the causes for infertility.Also, I suggest you to get an ultrasound done to rule out any uterine anomalies like fibroid. Thyroid abnormalities cause irregular and heavy bleeding. So kindly see a doctor and get antithyroid medications for hyperthyroidism. Once the thyroid is under control the chances of pregnancy increases. Nothing to worry. Relax. It is a treatable condition. Hope this helps. Best regards...
