I'm 30 yrs old ,single , height 5.4 , weight 57 kgs .I had sex on 1st (oral) & 13th March (penetrative but protected & later i had i pill same day).I got my periods on 21st march but they lasted 1 & half days 7 third day terrible watering happened .I showed ot to a gynaec.When she checked me there was white secretion from my breasts. She asked me to get thyroid checked ( I had thyroidism previously ) , my test showed high TSH levels ( TSH was on higher side & out of range specified ) .My thyroid doctor told me that I was having hypothyroid .Again I showed it to my gyneac , she did urine test & it was negative & said that thyroids are responsible for scanty periods .On 1st April she again did my urine test & it was negative .On 10th April I did lab urine test (which was negative ), serum HCG ( it was negative ie. 1.25) & serum prolactine ( within range , highest side was 29 , whereas i was on 26 ).On 13th April I got my periods but they again lasted for 1.5 days but this time watering was absolutely nowhere.Pls note that the gap between my march & april periods was about 21 days ( ideal cycle is 28-35 days ) On 18th I did ultrasound to check what was wrong with me.Radiologist said that I had polycystic ovary syndrome causing scanty periods.Also, what is the ideal time to check if ur're pregnant or not as I certainly donot wish any pregnancy .Pls could u tell me what is the actual stage I'm in ? Frequently I feel giddy, acidity & constipation.Still at times I find slight secretion from the breasts .Off late i find my belly appearing .What exactly is causing scanty periods ?Am I normal ? Will I get my next periods properly ?Pls help
