Sunday: I missed a pill

Monday: I took Sunday's pill and since I was out, I didn't notice

Tuesday: I missed a pill again

Wednesday: In the morning, I took Monday & Tuesday's pill then I took wednesday's pill (11:30pm; usual time) 

I'm currently on vacation in the beach with my fiance and we've been having sex. We would do it raw first then he would wear a condom later so technically, he doesn't *** in me. Before we go at it again, it's a span of hours plus it would be washed away by either the shower, cold ocean water or his pee. I don't plan on getting pregnant yet with the dress and stress of the wedding. If it helps, I've been on the pill for a year and a half. 

So basically, I'm wondering these:

Will I ovulate?

What are the chances of getting pregnant?

Is it normal to have slight breast tenderness and slight nausea cause of the pills?
