K.T.
If you're not sure you want to go through the whole baby thing again, then don't do it! However, I will tell you that I had my second daughter in May of this year (her older sister is now 2-1/2) and they are both the loves of my life.
I was put on bedrest at 33 weeks with my first pregnancy because of high blood pressure, but I didn't have any complications at all with my second. If potential health problems are scaring you, I would strongly suggest talking with your doctor to get his/her opinion. I was told there was only about a 30% chance that I would have the same complications the second time, which meant there was a 70% chance everything would go smoothly ... and it did. :)
Good luck making the right decision.
