Could I be pregnant?

April

Having cramps on and off and my boyfriend and I use the pull out method and I went to the restroom earlier today and noticed a light pink color of blood when I peed but I don’t know what my body could be telling me, I’m not on birth control and we’re careful but I am in so much pain right now with cramps it’s not funny and it’s been on and off like I said before. Please help ?
