could I possibly be vomitting an severly nauseated 4days after possible ovulation? Signs of pregnancy already?

Answer 1

i started getting nauscious when i was only about a week pregnant. the placenta has nothing to do with considering, you don't even have a placenta until you are about 10-12 weeks along. you have a yolk sak that the embryo feeds off of until the placenta forms. by that time, the nausea will probably be gone.

Answer 2

I dont think you get nausea that early in the pregnancy. because you usally start getting it when the placenta starts devloping cuase it pumps out homrones. Right now your baby might not have even implanted in the wall, then for several weeks you just have a yolk sakc and dont have a placenta yet. I think its more likely something else cuasing the nausea.
Here is the page talking about how the placenta makes the hormones:

Answer 3
