Illness at 23 weeks 5 days

So I'm really worried as I've had a bad cold for the last 3 days now ( eating and drinking as much as I can )
I woke this morning with a really sore throat each time I coughed ( which is a horsey cough ) felt like my throat was being ripped apart I had to run to the toilet to spit mucus out which was browny and noticed fresh blood too. Phoned out of hours and they say strep throat is possible but I am unable to make it for an appointment until Monday. They advised me to take paracetamol and drink plenty of fluids yet I'm worried sick as it says alsorts on the internet. I'm concerned for my baby more than myself will I be ok until Monday? :-/
