How hard should I push for diagnosis?

I've always had very painful period cramps and heavy bleeding, enough that I missed class all the time in high-school just lying in the nurses office with a heating pad. I've had recurrent itchiness and swollen everything during periods that only stopped when I stopped having periods on birth control. I could never wear a tampon or handle penetration because I have no natural lubrication

It's been getting worse though, I'm now cramping more than when I'm just on my period. It's at least once or twice a week. It gets worse when my heart rate is high, and my feet ache very badly. I'm sitting here trying not to vomit right now because I made the mistake of drinking coffee

I saw my gyno a week ago and she said my symptoms sound like endo but that they won't give me a laproscopy until I'm wanting to have kids, since the scarring can cause birthing complications. It sucks because I have no wish of having a kid right now but it's hard to convince them that when I'm 21.

Is this about the time I should start pushing very hard? I know it takes an average of 10 years to get diagnosed so I'm not sure if I should just keep bringing it up at yearly appointments or push harder. I'm the sort of person who treats everything lile an emergency so I don't know if I'm jumping the gun or not
