impending miscarriage

I hate light spotting two days ago, they sent me in for betas that night. They came back at a very low 169 😢 they sent me back in today for more. Although I haven't had spotting in almost 24 hours, my levels were only up to 188. I have to go back on Monday for more monitoring. I'm so sad I'm crying but have to try and keep it together for my three kids. Doctor seemed optimistic it was just still early but said it's just inconclusive at this point. AF was due 4.15 I got my first positive on 4.19. I'm devasted I will likely lose this pregnancy 😢
