I had sex the day before yesterday with a guy, and it started to hurt alot and since then i have had a little bit of abdominal pain, and tonight i had sex again with him and it hurt really bad i had to tell him to stop. It hurts a little to sit down, and walk, and if i push on my lower stomach it hurts, i don't know what it wrong and i really don't want to go to a doctor unless it is necessary
