10 days late

I’ll make this short as my phones about to die!

So my husband and I have been trying for baby #1 for about 2 years but only seriously trying for a year.. my periods have been irregular for a about a year or so and I went to the dr back in November/ December and she put me on BC so I got off it in February and my periods have been consistent since then so my period was due on th 5th of this month and it never came I’ve been worried because either I could be pregnant or my periods could be just going back to being irregular.. so I tested and it was negative and I just went to the bathroom and wiped and there was a thick clear discharge (pic attached) not sure what’s going on and I called my dr and they told me I couldn’t come in unless I tested positive so if anyone has had any experience please lend me some advice
