35 weeks and 5 days with Nausea

I'm currently 35 weeks and 5 days pregnant. Having my son at 39 weeks on July 25th unless he decides to appear earlier. Or if anything goes wrong such as blood sugur numbers aren't consistent/ in a range they like. At around 30 weeks my morning sickness came back and I've been throwing up i was giving something to help along help with heartburn. That actually helped. But now i haven't had heartburn in a couple weeks and it's not helping. Has anyone had morning sickness or nausea come back 30 weeks or further along?
