Pre cum on fertile week, the day before ovulation. Chances?

First day of last period - around the 23 of November

Day of sex- 12-5

We basically used the withdrawl method, (I understand that it is not 100% effective)

Does semen every seep or sneak out a little before actual ejaculation? ( I am not talking about pre cum)

Also, he ejaculated on my lower hip and it dripped down. How far can those little swimmers travel? I'm not sure if it actually touched my vagina hole, because I was sweaty. (I'm trying to make it as mature as possible)

Lastly, My ovulation weeks are never ever like this. I never even understood that there was symptoms of ovulation till now.

If I sneeze, my bladder area cramps for a couple seconds. My left ovary side has been non stop crampy as well. Plus nauseated. I understand that its too early for actual symptoms. When should I take a test? What are the chances? Similar stories?

I also used a vibrator one hour later, and didnt shower beforehand.

Thank you!
