Terrified of miscarriage

A
When will this end? Every time I go to the bathroom I am expecting to see a pool of blood. I've been spotting on a few occasions and just found out that I now have a yeast infection which I have to treat with monistat which freaks me out! I saw my baby again yesterday via ultrasound at 9 weeks because I was having spotting. This is soooooo stressful!!! I thought pregnancy was supposed to be enjoyable?
