Help concerned

I KNOW I ALREADY POSTED BUT THIS IS IN MORE DETAIL AND HAS A QUESTION

So 67 hours ago me and my bf decided to take a shower togheter and things escalated quickly. Also it was the last day of my period and I’m not really aware how ovulation work but the app says it’s today. But basically I was standing up on the sides of the bathtub/ shower and we were making out. He was fingering me and I was diving hung a hand job, I was elevated and all of the sudden he came. He said his fingers were still in my vagina when he came and I think that if any sperm even went close to my vagina it could’ve not gone in because his fingers were still in there and like technically his hand was covering my vagina. After I realized I had cum on my hand he took out his fingers and moved his hand I grabbed the soap and washed my hands and then rinsed them.

I GUESS MY QUESTIONS ARE:

1. Could sperm have entered my vagina?

2. Was washing my hands enough to get rid of the sperm on my hands

3. Should I take PLAN B since it been less than 72 hours

4. Could I be pregnant

5. And if it was before my ovulation time can I be pregnant

And here is a kinda of way of showing the situation.

Impossible RIGHY?
