Stressed out, please read i Need support..

About 2-3 weeks ago, i had a surgery of My Fallopian tube/ oviduct, so i had one of them removed after a etopic pregnancy
I've had cysts on My other oviduct several times. 
And i overthink this so much, " what if i get cysts on it again and the're so bad i Will Need a surgery on the oviduct i have left also Will be removed".
I'll be 20 this year, so im not that Old. But i've Always wanted kids, at least 3. so if i couldn't have children on My own i'd be devistated.. 
So im really Stressed about having a child. I want one now, i've wanted it for so long, but now after the surgery im SO sure i want one right now. 
But my boyfriend isn't ready, he wants to travel, he's insecure about money, and he think we're too Young. 
I agree we're young, and i try to save money so We can travel around. But then when we have Done that, We wont have any savings for a child, for all the child needs. So it Will take forever to even get him satisfied with the thaught of having a baby. 
And i am Getting more Stressed the more i think of it all, but if he don't want a baby now i can't force him. I've told him what im thinking and all. But he says " If We can't have our own children, We could always adopted a baby".
But i don't want to do that, i want My own babys, i have the possibility now and i don't know about tomorrow..  It's possible it wont be a problem for us to get preganant in the future, but We don't know that today, and i don't want to risk it.. 
I really don't know what to do.. I Love him so much. And i want him to get confortable in the thaught of having a baby in a year or two. 
Anyone else who has been in the same situation? That you're ready but he's not? 
What did you do?
