So nervous

So, I had a blighted ovum that required a D&C; in January of 2017. My first normal period after that was January of 2018, and we have been trying since then. Last Thursday, I got my first positive test. They are still positive, but I got a + on a digital on Sunday, and a - on the same brand of test today (equate digital, maybe it’s the test?). My cheap tests still have a second line, and while it’s not fainter, I don’t think it’s getting darker. I also have had some spotting, but nothing that would generally cause alarm. I can’t get into my doctor until next week, but ladies, I’m so nervous. I’m still finding that my stomach is upset, but my breasts are calming down, but still sore. I don’t know how I will handle this if I miscarry, and unfortunately, I’m preparing myself for that to happen. I was so ready for my rainbow. I’ll update when I see the doctor, but I don’t know how long the results will take to get back.
