I had follicular study and took 2 times 2.5mg letrozole for 5-5 days egg size grew to 19mm on 18th day and given injection in stomach to rupture. But on 21st day they said it has turned into haemorhoggic cyst of 2.6×2.8 cm. I used to get period with in 28-30 days but now it's 31st day and didn't get period took home test on 30th day it came negative.. I am feeling acidic fatigue and nauseating (I feel very little when I am gonna have my period).had other egg sizes of 17mm and we had relation on 22nd day once only. Can I be pregnant or it's hormonal imbalance?
