Menstrual pain?

Stephanie
I'm 7 weeks pregnant, had a miscarriage last year at 10 weeks (stopped measuring at 6) so naturally I'm nervous! 
I don't really feel any symptoms of pregnancy anymore, I've just been feeling pain like menstrual pain but no bleeding touch wood. I just can't shake the feeling that something has gone wrong again. I know that they won't do a scan unless there's heavy bleeding so I've been doing the odd pregnancy test to see if it goes lighter or not and it still says I'm pregnant but the line was streakier than normal. 
I can't sleep I'm so freaked out by this pregnancy!
