Can anyone help please?

Chloe
Me and my boyfriend have been ttc for 5 months now and when we got together I had a miscarriage at 8 weeks, March we decided we wanted to try for a family.  o I last had a normal period on the 8th of July and this month I was four days late and I took a hpt and it came back positive but with the faintest line, I woke up Thursday feel very tired and just "off" then about mid day I started to have a pinky discharge then an hour later It got heavier getting a reddish brown colour with clots then stop and started all over again about half and hour later, I have been getting cramps in my lower abdomen for a week now and once in a blue moon I get the odd pain that makes you want to be sick. Can anyone help me please? (Sorry for the detail)
