Endometriosis?

I'm New here. I'm not diagnosed with endometriosis but it is suspected. I told my ob/gyn about pain related to periods. I have always had pain with my periods. In the beginning it was only the first couple of days, Then i started to have pain with ovulation and before my period (usually 5-7 days before, but it has been pain on and of up to two weeks before my period starts), and when i talked to gyn about it, it also lasted through the Whole period and even a couple of days after the bleeding stopped? Anyone else experiencing this? I'm so tired of having pain and how it affects my life. And i also has experienced pain during/after intercourse. Last time i was taking oral contraceptives, I still had a lot of pain during my periods. Gyn told me it could be endo, and gave me prescription for contraceptives and naproxen (250 mg x4 per day for 5 days. Starting one day before expected period). I'm going to try this for 3 months and I will meet her again. She talked about lap. but we'll see after 3 months. I haven't had any period yet after staring the contraceptives. If it's not better after this treatment, i want to have a lap. At the same time I'm afraid that they won't find any reason for the pain. I have been reading about doctors Who tell their patients "it's all in Your head, it's nothing" etc. My ob/gyn is a really Nice, but i don't know how Others doctors are. My question is if you think I should have a lap ? Any experiences?
