Pregnant

Stacie • 21 and have a beautiful boy named Freddie born 13/09/2016
I have got what my best friend says looks like a bump. I have had cramping and I'm so bloated. I have irregular periods but I usually know when one is coming on and this isn't happening. I'm nauseous and sick and I have very very visible blue veins all over my body which I haven't noticed before. Could I finally be pregnant or is this just in my head
