Not everyone has morning sickness in pregnancy and, while it most often happens in the first few months then subsides, for some women it can happen throughout, or stop for a few months then return towards the end.
The white discharge can be perfectly normal... unless you notice a strong odor or have itchiness in which case it may be a infection.

Certainly see your doctor again whether you are trying to get pregnant. They will determine whether you definitely are or not and discuss how you might be able to help get your periods more regular which is what they will likely look at first.
