How long can an ectopic pregnancy last?

ali
Im very worried because I'm 11wks and 2 days gone with my pregnancy but haven't seen a doctor yet because of insurance issues. I'm in the process of getting medicaid but it's gonna take weeks to be ready. Thing is, I feel pain on the left side of my abdomen when I compress it. This is my first ever pregnancy and looking at what causes ectopic pregnancy online, I think I'm not at risk but my conscience won't let me stop thinking about it. I was thinking about just visiting the E.R without insurance for now but I'm scared of the bills. ... what do you suggest guys. Thanks in advance
