Serious question! Please read !!

I choose to remain anonymous! I am 22 my bf is turning 24 Tomorrow! He took my vcard at 18! And after having sex and not getting my period regularly i had a pelvic exam! A few months later because my mom didnt know and i was scared to tell her i was having sex because she threw me out alot over stupid things! And shortly threw me out after i opened up anyways after my appt i got a call from my obgyn saying i had clamydia but it wasnt severe so i could take a antibiotic and refrain from sex for 7days in which i didnt take lightly and didnt have sex! Now here i am with pcos years later and im having trouble conceiving weve been having sex without condoms since i was 18! Well ofc at first we did use condoms but stopped after we were serious dating! Im wondering if this could have caused scarring or blockage in my tubes! I have an appt on thursday next week with my obgyn! And i dont know how to bring it up to him! Is there a way to check this without surgery? Im prone to keloids now and i dont want scarring on my stomach :/ but idc if i have to i have too! Any experience with this or having blocked tubes and having it fixed and later getting pregnant naturally! I was placed on clomid and we havent been successful for two rounds ! So im thinking something deeper is wrong ;( i want to be a mom so bad :(
