When to call doctor?

So yesterday I started feeling off. I have a headache, nausea, and feel dizzy and off. I’ve been taking my BP and it’s high for me but lower than what my doctor told me to go in for. I haven’t been sleeping at night and I’m not sure if that’s what’s wrong but I just feel really ill.

My husband and I just got back from a week long honeymoon so I’m not sure if I’m just feeling exhausted from that or what’s up. No fever, no vomiting, nothing else going on. But I feel absolutely atrocious.

Not sure if this is normal 3rd trimester stuff? Don’t want to call and look like a dummy if this all sounds normal. Baby is moving a lot as well.
