Taste changes

Anyone had taste changes when pregnant? I am seven weeks. Yesterday I bit into a piece of cheese and it tasted like straight mold but there was no mold on it and my husband said it tasted fine. Today I tasted a few other foods and they tasted bad as well but they weren’t. Is this a pregnancy symptom? I’m not nauseous at all. Oh and I was at my mother in laws and her coffee tasted HORRIBLE but I thought she just had bad coffee. Now mine at home tastes bad to me too.
