Loss of symptoms at 6 weeks

Alissa • Living in Northern CA with my husband, three year old little girl, and our Puggle working in the ER & loving life :)
Anyone have experience with this? Started off week 4 with VERY tender breasts, and week 5 I had 7 days start of multiple episodes of vomiting and constant nausea. Today and yesterday ALL symptoms have stopped. I know this is a sign of miscarriage and I am so stressed...I've had 3 already, and just recovered from a Molar Pregnancy in August. 
Any advice!?
