cramping at 5 weeks

anyone else get identical period pains middle of 5 weeks or around that area? 5 weeks 2 days my HCG blood was 185 progesterone was 9, I get more blood done today at 5 weeks 4 days to make sure it doubles and I find out tomorrow morning my results. I woke up in the middle of the night around 3 AM today with identical period pains abdominal and lower back but not bleeding, its just my white creamy CM. I had one ectopic 4 months ago which was my first pregnancy and I'm positive this isn't another one but I'm so scared of MC!
