pregnant after miscarriage

Hi all. I'm 5 weeks pregnant with my rainbow baby 🌈 after suffering a m/c of my first pregnancy in Sep 2016. I have been spotting since implantation bleeding on 8 dpo (so almost 2 weeks). My OB has me taking progesterone suppositories. This time around, I am and have been taking prenatal vitamins (I wasn't last time). I have been praying so hard that I can keep this baby. I've also been trying to visualize being very pregnant and giving birth in November. But I still worry constantly. I'm always going to the bathroom to check the color and amount of spotting.
