Constant headache 38 weeks

I've had a headache pretty much constantly for the past week. It's not really bad, but it's definitely there. I mentioned it to my doctor the other day, but she wasn't concerned at all. I drink enough, and I've taken paracetamol but nothing seems to shift it. Should I call the midwives or? I dunno what to do. I don't want to waste their time by going in if its nothing to worry about. 😬
