Go to the doctor for a consultation. We can give you our opinions but it's not like we are really professionals. The EPT test is very accurate but get a blood test A's well to confirm. Not sure if you want to be pregnant or not but mat want to consider birth control such A's the pill plus condoms to lessen STDs. It's probably a scary time for you and I feel for you, having been there myself. Do act in a timely manner so you can make the healthiest decision possible, if need to. Connect with a gyn soon and establish a working relationship. Lastly, try to limit unprotected sex. It is hard to do in the moment and I am no angel on this matter. Just passing on what has been helpful to me. Good luck and try not to beat yourself up!
Warmly,
