Discharge?

Hi, so I just had sex a couple days ago for the first time in a month. And now (yesterday and today), when I pee and go to wipe I have A LOT of discharge.

Yesterday (TMI) it was like snot. Today it’s extremely watery.

We used a condom and when we checked afterwards, there was nothing leaking out.

Just curious as to what this could be. I also have an IUD and just ended my period end of last week.

Thank you!
