Help... About paternity testing

So my Dr said based on my last period i got pregnant around April 14th. Just found out I'm pregnant with they guys I've Ben with. But we were broken up a couple months ago and march 10th was the last time I had sex with the other guy... Well I had a period after that and my current boyfriends (ultimately been together 3 yes) mom is saying he needs a paternity test to be sure, he's 100% there for me tho but wants to be sure its his. His mom keeps telling him girls can have their first period when there pregnant even tho I took tests when we got back together just to be sure ! And she still says well tests don't show for awhile. Ugh so he wants to get one done just to be sure, is there anywhere u can actually go to get one done ? Instead of mailing it... We live in Florida...
