Faint lines, rainbow baby!

Hi ladies! I am 14DPO today, but only about 3 weeks 4 days pregnant by LMP. Are these lines too faint, or is that standard for being so early? I did get an HCG blood draw yesterday and my levels were at 51. Really hoping to see them double after my draw tomorrow! I had a MC back in November, so I’m struggling to not be extremely anxious. I have a 3.5 year old and just want him to be a big brother so badly! 🫶🏻 How do you make it through when every single moment of every day is consumed with thinking about it/fearing losing the pregnancy?!
