Aspirin and endo .. please help!!

[Wishingforabump]

Hello everyone ,,

Just wanted to ask i don’t know how dumb my question is but i will go ahead to clear my mind . I have been taking aspirin81mg daily for my FET , i have been having awful pain since 4 days only relieved by Advil every 6 hours ... i went to the clinic and my endometrioma is 10cm now .. i have had endometrioma before 8 and once 20cm but never had this horrible pain ( knowing i just did egg retrieval 2 weeks ago) .. i know hormones , my ovaries are enlarged from medications .. but this is my 3rd cycle and the pain is very new to me .. i started questioning could be the aspirin growing my endometrioma or aggravating my pain ? I know its the other way around since its anti inflammatory but i am trying to rule out any cause of this pain
