So I had my baby girl Nessa July '17. fast forward. she is going on 8 months old and I just realized yesterday I'm 10dpo. husband kept telling me to take a test and finally I did. big bright and red, 2 red lines. I'm so freaking out. took us a year to get pregnant with baby girl. 2 young babies and a 5year old. any advise? will this pregnancy be ok being I just gave birth 8 months ago? 3 kids will be alot. I'm only 25😣
