IUI, endometrioma

I don’t know if anyone has a similar situation but I have a 5 cm endometrioma and not sure if I have endometriosis or not. Some people say a endometrioma means you have endometriosis and I don’t know what’s true. Anyways, I was given Femara this cycle work a trigger shot and IUI .

I am very negative that this is not going to work and now worried this will create the cyst to get bigger. I haven’t seen anyone on here who’s in the same situation. Just need someone to shine some light that maybe things will be ok.
