Nausea and then no nausea?

Hi everyone I am curious to know how many of you are feeling sick and then one day not feeling sick at all? Wondering if this is normal.. or if anyone had a successful pregnancy when that happened? Ive had two miscarriages the last one I had barely any symptoms and no nausea but for this one Ive been feeling sick and having serious food aversions but today I feel better. Hoping all is well! Please share your experiences with it so i can have some peace on my heart.. praying to be a mom in the name of Jesus
