STD tests?

[72kcoh]

So iam pretty sure i got something bad and need to get tested. iam having alot of trouble finding somewhere to go. ive googled std tests in my area and cant really find much except for a few places that charge like $300 to do it. Is this normal.. I have health insurance, will they cover this? can i just call a regular doc;s office and have them test me? any help appreciated thanks
