I need advice

I’m 38 weeks and last night I had flashing lights in my eyes and a really tight chest and cough (out of no where) so I had a drink and went to sleep. I woke up today and felt ok, came down stairs and I started to notice I had a headache which quickly shifted to a severe headache that I can’t get rid of with painkillers.

Should I ring my midwife or am I worrying over something as simple as a headache?

I don’t have any swelling anywhere, Iv barley weed today though. Which is unusual.

I don’t like to bother my midwife over nothing 😖
