Is it possible to be pregnant and not have any morning sickness ?

If you had sexual: Intercourse then pregnancy is always possible. Morning sickness is not required.

Not everyone gets it: Morning sickness is the reaction your body has to Hcg (pregnancy hormone). Some ppl get the same reaction to TSH if they're hyperthyroid. You can start getting nauseous at 4 wks, w/ peak symptoms at 6wks, usually stopping by mid-2nd trimester. Natural remedies are ginger (tea/candy), vit B6. Rx: Metoclopramide/Reglan, hydroxyzine, benadryl, phenergan, (promethazine) and zofran are all good methods to try.
