Wierd

So i stopped bc in may ... june i got a regular period , july i got a period same day as the previous month, august i got a period same day as previous month , sept 14th i had sex & boyfriend came in me ... period is 1 week late . Negative pee test , blood test & ultrasound (my dr wanted to cover all bases) i thought for sure i was pregnant but i guess not .

Dr said i could have simply just not ovulated this month, and proceeded to tell me i have a cyst on my ovary. Im just confused as to how out of nowhere i get NOTHING 🤷🏽‍♀️ no period .. no ovulation possibly . Wheres my egg 🤔 where did the sperm go 🤔 wheres my PERIODDDD 😩
