Is it normal for nausea to get better?

I’m almost 8 weeks pregnant. I got a cold and am stuffed up. I’ve been dealing with bad nausea since 5.5 weeks and even started Diclegis two weeks ago. The last two days, I noticed my nausea got better. Is it normal for it to get better? Not bleeding or cramping and still feel tired and bloated. Also, we heard the heartbeat at 6 weeks sonogram. Praying this is okay.
