I have been experiencing extreme nausea and morning sickness throughout the day since I was about 4-5 weeks. I will be 7 weeks tomorrow and since I woke up this morning I haven't felt sick or bloated at all. Since I realized I was pregnant I haven't been able to eat or keep down anything and now my appetite is back. I experienced morning sickness at least once a day throughout my entire first trimester during my pregnancy with my first son so this is very alarming to me. I called my ob/gyn and they can't see me till later next week. Should I be worried?
