My missed miscarriage

I had a missed miscarriage in November at 12 weeks so I've just found out I'm 4 weeks and 3 days im constantly on edge I'm having period like cramps but I no that's normal to start with as I've had them before but every pain I get scared everytime I go to the loo I wipe for blood I'm so scared the anxiety I'm feeling now it's crap so has anyone got any good copeing techniques that I could use ??
