Trying not to worry. UPDATE

This is my second pregnancy, and I spotted a lot with my first. I forgot how stressful these first few months are....

I'm 4 weeks today and started spitting last night. Its mostly brown, some red, and not painful. I have an appointment tomorrow to check on things. I'm mostly worried because my pregnancy test lines were pretty faint, though I did get a good line Saturday. It's so hard not to worry!!!

UPDATE: I'm definitely miscarrying/had a chemical pregnancy. 😕
