Should I worry??

I’m 5 weeks pregnant and had a miscarriage at 5w4d last July. So I went to the dr. last Monday, they confirmed my pregnancy and ran a progesterone test. (My mom had 3 miscarriages due to low progesterone). Today I went to the bathroom and had MAYBE 3 drops of blood total. Fairly red. I’ve gone to the bathroom another 2 or 3 times since and have nothing. I was a bit crampy earlier but I also think part of it is in my head due to worrying. I’m trying sooo hard to stay positive. I called the hospital and spoke to a nurse that helped, but she said she really didn’t have anything definite she could tell me. Just needed some opinions. Should I call my doctor in the morning? (she was closed already tonight when this happened). Or should I wait for my appointment I already have on Friday?

Am I right to feel worried? Or is this normal and I need to relax?

*my progesterone levels as of last Tuesday were 16.56
