AM I PREGNANT?? HELP!

[Nickie2234]

Hi, I'm not sure if you'll read this but I need some advice. I had sex with my boyfriend on the 28th March, a week before my period was due. My period came normally on the 7th April, felt like a normal period as it was heavy like my usual. However, it's 27th april now, my next period is not due but I'm slightly worried as I've been experiencing streaks of brown discharge and slight(?) cramping (few mins) when I consumed a cold drink today. I'm not sure if I'm too paranoid as I googled the symptoms and it could be pregnancy? However, since I got my period on the 7th, it should be impossible right? Thank you so much!
