Are they getting darker?!

Kennedy • Married to my soulmate since 7.4.2020!💍💞 We have a 4 year old son, who took a year and a half to conceive! We are expecting baby girl March 11th 2021 after 2 1/2 years of ttc with fertility treatments 💖
2 days ago I went to the ER to get checked after I was having alot of pain and I got a + hpt. After they ran tests they told me the levels were only 57 and that I would most likely miscarry to come back in 2 days to get checked again. Ive been testing and testing everytime I pee since. I just wanted to see the line get darker and know if my little jellybean was growing. And the bottom one I just took and its pretty dark compared to the rest! Opinions ladies??
