Im 16 weeks this week..     Unfortunately im not allowed to exercise or run around cos the other night i started bleeding a little after my pregnancy classes.  Cos im negative in blood this means i have to rush to my doctor then to the hospital to have blood tests then have an injections within 72 hours of bleeding.   IT SUX HAVING NEGATIVE BLOOD.   But the baby is ok through this..     My hubby is away in tasmania for work and im enjoying having a quiet house.
