Has this ever happened to anyone ?

So me and my partner currently have 2 children that we had back to back, 16 months apart… my youngest turned 2 in February and I took a pregnancy test yesterday like I always do every month since I am not on birth control. I was hit with a BFP!! With my 2 other children I have never ever gotten this dark of a line on a dip test… my last period was June 24th… I have so many different emotions right now… 3 kids at 25 years old… has anyone had 3 back to back like this and how was it??? Also what could the super dark line mean…. Twins?😭 they definitely do run in the family… idk hormones

have me all over the place right now
