I had a septoplasty 2 weeks ago and my septum feels more sore than it did last week. I've also started to get blood appear again

Not loads and loads but am mainly getting blood appear down the back where phlegm gets into the mouth and spotting from the nostrils. Some in the morning, I assume from snoring, but also getting it before bed and throughout the day. This had completely stopped in one nostril but has started again. I also keep sneezing and try and do it though my mouth but it still hurts afterwards. I didn't have splints fitted after surgery and also had the packing taken out a few hours after the procedure.
