I am 32 years old, I am planning my baby now. I had gone through an abortion in March 2010 in the 22 week of my pregnancy. I have consulted a gynaecology doctor and got all tests and ultrasound done. All reports are normal only my thyroid (tsh) was 5.2 so doc asked to take THYRONORM 25 mcg and a folic acid tab. Since the last 2 months I feel a small acne type structure on the left side of my virgina wall. I took is casually initially and it had reduced in size but since 2 days it has grown up again. It does not pain nor there is itching. But what is it? Why has it come? Please advice.
