3rd time mom feels like first time mom

Sisi
I'm 6 weeks pregnant but I have a 15yearold & a 10 year old lol.. This pregnancy is so different from my other two.. Cramping, nasuea, just miserable.. But I'm excited because I didn't think I could have anymore kids.. I'm praying for a healthy baby girl.. My other two are boys.. This pregnacy is just so different maybe cause my body not young like the other lol.. My due date is February 17..  Google has been my best friend since I found out I promise it's like I'm a first time mom lol
