Pp

Hi can I have a pp please?? So basically I came on my period 3rd July lasted 5 days, not tracking ovulation dates or anything, noticed abit of browny pink discharge on Wednesday and now I'm having severe tummy cramps I know Iv still got a couple of weeks till I am due on. Iv had unprotected sex and arnt on any form of contraception. Has this happened to anyone else? Searched online and mixed signals between seeing my gp for an water infection or if it's just the egg attaching to sperm or nothing at all? Lol xxx dusky pink color wears for bridesmaid
