Late first appojntment

Found out I was pregnant with at home test, my estimate Is 5 w2d. I called all the obgyn offices.in my area that take my insurance. None would see me until 8-10 weeks along. I explained that when I had my daughter, my doctor said I wasn't developing as I should be but me on partial bed rest, and gave me a progesterone suppository so I wanted to be seen sooner to be sure I didn't need the progesterone again. My appointment is in 3 days, but I have light spotting. No cramps, but I didn't have bleeding with my daughter. I'm kind of panicking. My husband and I have been trying for a while just to get pregnant and I really don't want to lose this baby. I have been eating a little better, drinking alot of water, and taking store bought prenatal vitamins every day.

I guess my question is, has anyone else been in the same boat? What did you do? What would you do?
