Okay ladies so I am a week late for my period. I took a test at 5 days late and it came back negative. I am gonna take another test but I am kinda freaking out cause my sil had a dream that someone in the family had twins with dark hair, I am the only one in the family who can get pregnant. 2 of my sils are fixed and the 3rd has to take medicine to get pregnant. I am kinda freaking out cause twins run in both my fiance and my families. The last time anyone in his family had a dream that someone was pregnant it was my mil and a week later I found out I was pregnant with our son. So I want to kinda prepare myself just in case I am pregnant and just in case with twins how in the world do mom's of twins do it? I Am a stay at home mom and I kinda struggle with one lol but a lot of that has to do with ppd so please ladies I need advice on what to do!
