Symptoms before labour

I'm 38 plus 3 today. I've woken up with such a sore throat and feel quite fluey. Has anyone experienced this before labour. Babys head is 2/5 so classed as engaged. I had a bloody show about 2 weeks ago and keep loosing mucus every day. I hope this is a sign of labour. However I am having a stretch and sweep on Wednesday. So fingers crossed.
