Could this really be?!

A • Mommy of 2!! Baby 2 arriving 12/22🥰

Got this this morning with FMU. My last cycle was March 13th so according to this app I’m 3 weeks 3 days. Is this a pretty dark line to be so early? Or could this be false? I thought maybe it was too dark to be a false. I’m scared to get excited. I’ve had a chemical before. But I’m really hoping this is my December baby 😭😍😍😍😍😍😍😍😍❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
