Re: Running while pregnant
You need to check in with your doctor. There are many conditions, including blood pressure issues, that can impact a training program and, more importantly, your baby. I know many doctors tend to be conservative, but if you indicate that you are willing to be responsible and careful (as you are being, according to your post), he/she will probably give the ok. But whether or not you should continue running is absolutely not anything people can "diagnose" from the internet.
FWIW, and you can certainly take or leave my experience, having a sick or premature baby is just not anything you ever want to do. I know those last few months of pregnancy feel like they last an eternity, and you are probably very concerned about maintaining your fitness at this time, but believe me, in this case it is far, far better to be safe than sorry.
