Bleeding

hello, I was just wondering if anyone had anything like this happen to them or if they can give me a bit of reassurance (I’m panicking) At the beginning of Feb I had some fresh blood after sex - straight after which stopped immediately so I went to the gp to check it out and had a pelvic exam and swabs but nothing came back so that was it but recently I’ve had a bit of pink after (before it was bright red) I’m going back to my GP but I’m really worrying now having scared myself by googling - does anyone know what the GP might suggest - if he’ll refer me or give me another pelvic exam... I’m only 20 and I’ve never had a smear so that’s making me even worse!
