What are chances,, please reply with some logic

What is all of this 'meeting'? Do you mean you had intercourse? Please, be more logical in your posting.

If you want logic, you have to ask a question. What are the chances of what? Are you asking if you might be pregnant? Well you don't get pregnant from "meeting? So did you have sex or what?

What are chances of pregnancy and why interrupted bleeding occurred?

Any time you have penile penetration there is the risk of pregnancy. What the "chances" are we can't say. The more you do it, the greater the chances.

As to the bleeding, you should see your OB/Gyn about that. It requires a medical exam to really tell.
