AF round 2

Em
I feel like I'm alone. Has anyone ever taken progesterone to force their AF after a certain date in their cycle? How many times did you have to do it? Did it help you get pregnant? Were you ever diagnosed with anything like PCOS
I just started this journey and my doctor has high hopes by the end of the summer I should be pregnant but I just have so many questions and I don't wanna feel like I'm the only person going through this.
