Question about Discharge...

I’m 18 weeks and want to make sure my discharge is normal. I definitely have more of it than I did before pregnancy, and sometimes there is what appears to be egg white sticky/stringy discharge when I wipe. I scared myself into thinking that it could be part of my mucous plug... is it normal to have some of this type of discharge? Does anyone else have some of this more sticky, ovulation-like discharge at this stage?
