Today I am 7w1d. At the end of last week my morning sickness got so bad. I was constantly nauseous and threw up a couple times within several days. Now two days ago all the sudden I felt zero symptoms. Yesterday I had a slight bit a nausea in the evening but that was it. Does that mean I could miscarry? Have your symptoms come and gone or got better but then got worse again? My last and first was a miscarriage so I feel extra worried. Thanks!
