So 2 weeks ago me and my boyfriend had sex without a condom he told me that while he was pulling out he started ejaculating, I didn't think anything of it at the time but today at school I skipped lunch and usually its no big deal but I was sitting in class and I got intense sharp pains in my stomach. Also the past couple of days I have been getting dizzy when I stand up and going to the bathroom A LOT more(number 1 and 2). Could this be pregnancy symptoms? If not then what is it?

Every time you have sex there is a possibility of getting pregnant. You do understand that the pull out method is extremely unreliable? You may well be pregnant. You will need to wait and see if you get your period and if not, test for pregnancy. I am assuming you do not want to be pregnant, considering you're still in school? I truly hope you're above the age of consent also. You need to stop having sex if you are not ready to be a parent. No form of birth control is 100% effective.

Many symptoms of pregnancy do not start until the 4-8 weeks of pregnancy. It is very unlikely to have pregnancy just after two weeks. Pregnancy test at this time is most likely to be negative. I would advice to wait until your next cycle and if you don't see anything, I would advice to get a pregnant test. However, you should always take precautions when having sex bearing in mind that pulling out method is a very unrealiable way of protecting yourself from unplanned pregnancies.
