Faint positives for 4 days, doctors appointment tomorrow. I'm so nervous.

I have an appointment tomorrow for a urine test at the doctors office! I'm super nervous that they're going to tell me it's negative because of how faint my lines are. (They are VERY faint) They said they don't do blood tests there, which I know isn't true because I had my levels checked back in September. So hopefully they'll do a blood test to, in order to stop my wondering! Pray for me, ladies! I'm really hoping this is my Rainbow Baby. 💜
