I've had a cough for around 11 weeks now. It's not all day but seems to flare up in the evenings though it doesn't keep me up in the night at all. I don't smoke and neither does dh. I'm 21 weeks pregnant currently if that's relevant. I got a new fabric sofa round the same time I developed the cough and I've also been spending quite a lot of time sat on it with my laptop as I've been working from home for 7 weeks.
