I'm fucking stressed out of my mind.

So I have had a copper IUD for about 2years and I recently had sex with someone...he finished in me twice. My ex boyfriend never finished in me and I'm freaking the F*** out. It's been almost a week. I haven't had any abnormalities, except today I had a creamy white discharge....but I just started my ovulation today. Idk I'm just really nervous idk what to do.
