When I was uninsured I went to our local Planned Parenthood. Unfortunately I did not have a great experience, the NP would listen to what my problems were and treat me like that was impossible/I was lying to her. She was very dismissive and rough in the exam. She said "things might be wrong but I need to do an U/S and that would cost you 500$" [which we did not have so I did not get it] I got the birth control pills for free though, and as soon as I could, and my husband and I got insurance, I ditched the PP and the nasty woman working there.
I am sure everywhere is different, and they do cover the basics, depending on income.
I just had a "bad egg" in the dozen.
