I had a transvaginal ultrasound at 6 weeks and have had nausea and vomiting all day since week 5. I am 7 weeks today and have noticed my nausea is not very bad the last few days. And no other symptoms either ( other than sore boobs). After my ultrasound I had darker pink spotting with no clots and only for about 2 hours and figured it was due to the US and exam. Should I be worried that my symptoms seem to be decreasing at the 7 week mark?
