Do your taste buds change when you’re pregnant?

I feel like everything I eat is more heightened. If it’s sweet, it’s too sweet/ spicy, I can’t handle it. I ate a sandwich that had a spicy sauce on it that I’ve eaten before and it was toooo hot for me. I took one bite and 10 mins later and I can still feel it on my lips and tongue. Could that be an early pregnancy symptom? That’s not all I’ve been feeling lately.
