Getting winded!

So, I’m 16 weeks and 2 days and this morning I woke up took my prenatal and went to go make breakfast. In the middle of breakfast I started to get super winded where I thought I was going to pass out or puke. I ran to the bathroom and sat for a minute and checked my heart rate on my Fitbit and it was 127! I’ve been sick lately with nasal congestion and coughing but nothing more, other than having little to no appetite. I go to my doctor this Thursday but has anyone else been getting winded really easily? It’s scaring me a bit.
