Ectopic pregnancy. Please help

Have you had one? Please tell me what is what like. More specifically blood

I thought I was having a miscarriage. I am 5 weeks along. I wiped two days ago to a decent amount of mucusy brown discharge. Nothing for 12 hrs then a tbl amount of deep deep red. Then nothing. Then more dee deep red 6 hrs later. Massive cramping on one side of hip that comes and goes.  It'll be okay then Start up again. Little twinge of pain by my clavicle that comes and goes as well. Nausea   Headache. 

I've had several losses before. I always ended up bleeding bright red from the start.
