If there is a lot of clear discharge it could be that you have an infection in your uterus. If your baby's water bag leaks at all it can get infected and that will cause premature delivery or miscarriage. Stop having sex of any kind, don't take baths or swim only shower and stay off your feet as much as possible. It is normal to have a better sense of smell while you are pregnant but cramping could be a warning sign. If any spotting occurs with the cramps then go to the emergency room. Good luck.
I'm Moist With Clear Discharge Come Out N I'm Cramping A Lot Is That And I Can Smell Very Thing Do That Happen When You First Become Pregnant?
Cramping and fast smell is a sign of pregnancy but it is not a surety, if you are pregnant or not. If your period is 18 then you should wait and if it misses, you can take blood pregnancy test. This is the only way you would know the real truth.
