Someone help with this discharge...

So I am 13w 2d today and noticed I've been very wet the past couple of days. Anyways I got home today and noticed I was extremely wet and wanted to see what it looked like. Mainly I was curious because me and my SO had sex this morning and he came in me. Then I got up and got dressed for work. But I'm concerned because it's sticky and a little yellow. I had a tiny bit of redness on the toilet paper when I wiped this morning also. Probably just the sex??! The picture makes it look more yellow than it really is. The odor smells like normal discharge. I have no itching burning or irritation. My question is has anyone else had this or have any tips on what this may be?
