what does this cm mean?

So my baby passed away when she was 16 days old but I am now 7/8 weeks post partum....my husband and I want to ttc another baby as soon as possible. We want something to be happy about again...for the last week I have had thin lotion like cm and for the last two days have had the lotion cm along with some mostly clear stretchy cm that stretches a couple inches but still negative opks. ..so is my body trying to prepare for ovulation or is ovulation impending...and if so how much longer do you think until I obviate. My Dr gave me the ok to try and i have gotten pregnant all three times the first month trying...but just from others experience how long do you think I have until I actually ovulate...I also have between a 30-32 day cycle....if that matters...so help me out I want another baby more than anything
