is this normal?! 😩 inconsistent symptoms 6 weeks

I am 6 weeks 1 day and my symptoms are:

fatigue, cramping sometimes L or R only - sometimes both, excess saliva, stuffy nose, nausea almost constantly, VERY breathless even when just sitting down (i have to pause every few words to catch my breath while talking), brain foggy, bloating, firm lower belly, constipation… almost all of those are constant however, my boobs are only mildly sore to the touch? my nipples are more sore BUT the symptoms kind of decrease as the day goes on. I’m probably over thinking but is it normal for some symptoms to increase and decrease on a day to day basis? 🥺 TIA, trying to calm nerves after a previous early loss
