Weird symptoms.

Andrea

Last night 5dpo I noticed my heart rate was going crazy! I was just sitting on the couch and I felt like I was mid workout. I checked my heart rate on my Apple Watch and it was 119 bpm. It is usually in the high 70's low 80's. I also noticed a metallic taste in my mouth and I felt nauseous. I've never had this happen before so it completely caught me off guard. Are these common pregnancy symptoms. Or is it too early to have any symptoms?
