Jillian • Three angel babies waiting for me ❤️ Still waiting for my Rainbow 🌈

So I had what I thought was a normal period on November 25th. I started spotting on Monday this week, about three days after my period and it was light pink and brown. I had it for three days and began to cramp. I took a test on a whim and got a positive. Next morning I also got another positive. Went to the dr and he said his test was neg and it sounded like a miscarriage to him. I cried and cried, I didn’t want to believe it. They took blood and I will see my levels today but I took another test this morning and the line is darker. Shouldn’t it be getting lighter? I’m so confused! 😭

First test was from Tuesday night, Wednesday morning, Wednesday afternoon and then the bottom is this morning.
