I have taken four pregnancy test and they all were positive. I believe i should be abot 5 or 6 weeks along. Im having cramping, and feeling sick. My breast are sore and have gotten bigger i have also nosited viens in them which are very visable. Well im worried beacuse im not sure when my last period was im gussing jul 16-18. So this week i have been feeling like im on my period. Off and on it feels like im bleeding but every time i check theres nothing or a light white discharge. Im very scard and wake up thinking im beelding. I hope this is normal a misscarriage would crush me. :(
