Hi everyone just looking for some advice, I am 12po and yesterday morning I got the worst ever (felt like period cramps) in both sides I don't really suffer from cramping so it felt awful! Then I got what I thought was my period it was dark brown, then it was pink, then today bright red and now it has stopped! Can a period only last a day? Or could it be implantation bleeding? I was also weirdly emotional yesterday and spent the evening crying my eyes out! (My partner must think I'm crazy)
