New to TTC

My fiancé and I just decided to ttc. I've been off birth control for years, so I hope it will happen fast. This is our second cycle. I just ordered our vitamins and a super pack of ovulation strips. I'm excited, but I get a pregnancy condition called Hyperemesis which causes extream sickness. I'm praying I won't get it this go round. Has anyone else had this condition with their first pregnancy but not the second?
