TMI- question

I'm due to start my period in a week, usually at this stage I have little to no cervical mucus. For the past couple of days I've had a little bit of watery/slippery mucus (similar to ovulation) and then today it's plentiful and slippery/thick. I am so confused as to why. I had a miscarriage on December 23rd, 2014 and started trying again this month. Could I be pregnant???
