Early period and terrible cramps....any advice please?

[user1466661500]

Morning all :-)

I've never posted on here before but have read threads and hoping someone may have some advice before I bother the doctors.
I'm due on my period a week today and I'm always regular however I've been having terrible cramps and backache for a few days (I do suffer from painful periods but not as much as this!) Then yesterday afternoon I had extreme pain and started to bleed. Since then it's been heavy and the pain hasn't given in, I've had painkillers, and a wheat bag in bed, I've hardly slept as the pain was so bad and it's still not given in, usually after a few hours of starting my period it calms down a little. We're trying for a baby and last month I was four days late! Until then I'd always had normal periods and was on time! Is this normal?

Thank you for reading xx

Is the pain central or to one side?
It's too early to test but it could be an ectopic so do seek doctor's advice soon just in case.
