Is this normal??

Mya

So I am about 6weeks pregnant and I have been hit bad with nausea since I was about 4weeks... it’s usually everyday buuutt the other night I spent my head in the toilet for my whole 8 hour shift I couldn’t hold anything down and then I woke up fine the next day and today I still feel fine. Is it normal this early on for the MS to go away? I still have other symptoms such as sore and swollen breast and some food aversions but not as bad, should I be worried?!!!
