If you engaged in sexual intercourse you could be pregnant.

But your post is so hard to understand I can't say more.

if you merely masterbate no, you can not get pregnant, if the boy was there and sperm entered you, or he inserted, you could be. Your post is too hard to understand, as to what you actually did.

Periods can be a few days or more late all the time. If it gets to be 2 week late, you can do a pregnancy testt

Could be food poisoning. Will need to wait until into November, 2 weeks after your period if you miss it. Sorry to say it is a waiting game at this point.
