Worried

I am 8 weeks 2 days today. From week 5 to week 7 (even up to this Sunday) I have been SO nauseated all the time. No throwing up. But the last few days, I have not felt nauseated like I have been in the past. I still have sore breasts, peeing all the time, can’t sleep, hungry 24/7, and constipated. I am just worried about the nausea being less/gone. I worry a lot about miscarrying. This is my first pregnancy so I worry about a lot!

Is it normal for nausea to subside this early? I also should note that I have been taking Benadryl every night when I go to sleep to help me sleep and I wonder if that’s helping my nausea as well. Any thoughts?
