HCG levels

Marissa • My beautiful baby, Violet Elise was born on 11/23/19 via c-section 💜

So I went Tuesday 3/12 ( 17 DPO) for my first test.. I guess I was supposed to go for my second test in 48 hours but dumb me went the next day after 24 hours lol. I talked to the nurse today and she said my levels from Tuesday were 591 and my levels on Wednesday went up to 1375! She said it doubled in a day so I wouldn’t need to go again. This is good right?? I’m still holding my breath until my ultrasound on April 4th. I miscarried last October so I feel like I don’t want to let myself be excited. This is so stressful!! Lol
