Third trimester morning sickness

I had mild morning sickness in my first trimester (mainly nausea) and it finally eased off after 5 months. Well I'm about to hit my third trimester and I'm starting to feel nauseous sometimes and that weird sick feeling you get. I don't know if it's just the weather changing or if morning sickness comes back in the last trimester. I really hope it's the weather!
