You are very early so you won't feel like you're pregnant yet momma but if every test came back positive, you are! =) mood swings are very common in pregnancy due to all the extra hormones. Just take it one day at a time, before you know it, you'll be like me lol. I'm 27+6 and ready to have this baby.
Im 21 years old and my doctor told me i was pregnant i didnt believe her and bought a clear blue test when i left it came back clearly saying i was pregnant but i didnt feel pregnant and didnt really come to terms with it until that first scan at 12 weeks which was weeks after i found out. There was just something so different about seeing your baby on that scan and going wow i really am pregnant :)
I'm 20 weeks and 3 days and I still forget I'm pregnant all the time :p then I lay on my side and feel tiny appendages pressing on the side of my tummy and I'm like OH YEAH THATS IN THERE HEY
