Someone please help me understand


Today is day 23 I had a period but it only lasted 3 days ( NOT NORMAL for me ) I’ve been going to the dr and they are telling me I have a functional cyst. They have done a lot of ultrasounds and blood work - estrogen is high ( from the cyst ) and everything else is low. They did a ultrasound today and I have 2 follicles 10mm. The dr said once my estrogen comes down they can give me letrozole to help mature the follicles. Could my doctor giving me estrogen pills last month be the reason this happened? Is this going to be a new issue ? (This has never happen) is there any hope for this month ? Has this happen to anyone else?
