TMI Cm photo - what does this mean?

So I’m a little confused... for a few days/a week I’ve had dry, almost no CM at all. However today it seemed kind of watery? My period is due in two days and I have had sex this month (used condoms.) it doesn’t really smell of anything at feels watery and is clear. I took a Plan B pill last week - is this normal or am I pregnant? 😟😖 I’m not sure if I should be getting this type of Cm so close to a period
