Hi I'm 17 and recently I've had a stinging in my vagina with stomach pains followed with some bleeding spots.

My last period was on June 17th but it was 4 days late and my menustral cycle is about 30 days. On June 28th I had protected sex and the condom did not break or leak with a check of a few shakes and the feeling of the condom. On July 3rd me and boyfriend did oral play where he stuck his tongue into my vagina. For 2 days after that there has been a stinging inside my vagina where he stuck his tongue in. On July 5th he then fingered me. During this whole time I've had stomach pains. The day after that the stomach pains still occured but then I had blood spots.

Is this just caused by irritation because of my boyfriend or is this implantation bleeding? I'm really scared and I'm not exactly ready for a kid. Please help !
