I should be 6-7 weeks and now my HCG has barely risen in the last week. I really have minimal pregnancy symptoms. I have an ultrasound scheduled for this Monday but that seems like a lifetime away 😞 I’m preparing myself for the worst. I had a D&C in January at 10 weeks and am so afraid I’m going to have another one or am having an ectopic.
