ive started to notice light brown/ pink discharge in my knickers.. it started just 2 weeks after I came off my period and I'm worried I may be pregnant as I had sex with my bf as soon as I came off my period. But I've been reading around and everyone says their brown/pink discharge only last 1-3 days but mine has lasted a week so far. Also I haven't had any cramp or anything but I'm worried I may be pregnant coz unfortunately we was unprotected for the first time can someone please help me?
