Second baby❤️

So I am 12 weeks pregnant. I had my 5 months old baby Sep 1st and this one is due Aug 25. Anyone know what’s its like to have a back to back baby?? I know I have had extreme back pain and some abdominal pain. Only weird thing about this pregnancy so far is that I have had no sickness but with my 5 month old I felt like I wanna go die with being so sick. My 5 month is a girl and tomorrow I take blood test to see if it’s gonna be a boy or girl. I am team boy lol
