Why no periods for 2 months causing cramps?

Pregnancy is unlikely. Your period on the 29th would have been too early for implantation bleeding . Bleeding on the 2nd of this month could be hormone related, due to stress, or a vaginal infection. See your gynecologist for an evaluation and some blood and urine testing.

The antibiotic usage might alleviate symptoms temporarily, and yet the main cause of infection should be treated to avoid further complications. However, procrastination in treatment can cause sterility problems later on and, particularly during pregnancy. Thus, it is recommended to see a specialist and follow the prescribed treatment prescription.

Yeast infections can be quite bothersome, but there are ways to manage them effectively. They often cause itchiness, a brownish-white discharge that looks like cottage cheese, and inflammation in the area. Sometimes, even after treating other infections like ureaplasma, the yeast infection might persist. If this happens, you may need a different antifungal medication prescribed by your doctor to clear it up.

Experiencing a missed period, back pain, leg pain, and vaginal pain could indicate various underlying causes. Consult with a hyour doctor for an accurate diagnosis and appropriate treatment. 

You might have a disorder called menorrhagia, that is having heavy periods with clots. This problem may be due to hormonal imbalances or issues with the uterus. The heavy bleeding and clots you experienced may have caused some disturbances in your normal menstrual cycle. Consulting a doctor is essential for further evaluation and management. Treatments including hormonal therapy and procedures to deal with heavy bleeding can be the options that these doctors will mention to you.

When you are 15 weeks pregnant, the TSH level at 3.75 is a minimally higher value than the ideal range for pregnancy, but it remains on the safer side. So if you are not at the stage of subclinical disease, this parameter indicates that your thyroid is not far from the ideal range for pregnancy.

In this case there's no chance of pregnancy.
