Spotting

Nicole
Hi I'm 4 weeks & 3 days and have been spotting on & off for the last 3 days with light cramping. It started of as a faint pink & now is darker more brownish. I'm terrified because I had a miscarriage in November last year. We have been trying for 3 years now & I'm scared it's happening again. They drew blood yesterday & I go back again tomorrow. Trying to keep calm & stay positive but can't settle my mind. Feeling lost & out of control ;(
