Ive had all these the past 2 weeks but about 3 days ago the cramping and back ache got a little more noticeable not bad though, and also my nipples started to become sore and very sensitive they seem to be always erect now! even when i wear a bra, i can never remember them being like this. Today i've had a lot of gas pain in my stomach. Ive never had any of these symptoms before especially all together i have irregular periods so i don't know when to test. I was definately going to test this friday. Do you think i'm pregnant? Did anyone get any of these symptoms before??
