The 25-year-old announced she was expecting her third child, shortly after the reality star suffered a miscarriage with ex-husband, Javi Marroquin.

Fans are calling her next child a "rainbow baby" — a term coined for a child born after a stillbirth, miscarriage, neonatal death, or infant loss.

Things seem to be looking up these days for the reality star. She recently earned her Bachelor of Arts degree in Mass Communications from Delaware State University and plans on attending graduate school.

Kailyn is already mother to son Isaac Elliot, 7, whom she shares with ex-boyfriend Jo Rivera, and son Lincoln Marshall, 3, whom she shares with ex-husband Javi Marroquin. Baby No. 3 is due in early August.

Congrats, mama — we can't wait to meet your new bundle of joy!
