Okay, a week ago me and my fiance did the deed, and we didn't use protection. He did pull put but I know that doesn't always work. yesterday I had slight cramps and today I had slight brownish colored discharge by af isn't due for 2 weeks. past few days I've been insanely tired and just really upset. I just wanna know if there is a chance I might be pregnant and if so, when should I take a test? any help would be great. thank you.
