I'm out this month

Well ladies AF due tomorrow took two test today and got a BFN!!! I know she's coming on time too she always does. But I'm have a minor surgery it's called laparoscopy and a D&C and also a hystercopy on the 19th. I've talked to old women who's also had this done and I've been told it makes you very firtle. One lady had tried EVERY type of help to have kids she tries for 10 + years and 2 months after having the surgey she got pregnant. Her story is amazing. She has 4 kids now two are twins. Can anyone shed some light on this surgery for me?? If you've ever had it done or know someone that has... I'd highly appreciate it
