You haven't stated this so i have to ask ... Have you actually had a significant pregnancy risk? Were you using protection? Are you and your partner trying to get pregnant?
We don't advise that people go by symptoms of pregnancy ... Often times, it's way too early for symtpoms to even appear. Most women don't know they're pregnant until they've missed at least one period.
So, when is your period due? You can wait until you're due for your period, and if it doesn't come then, you can take a test. If you're curious now and it's been 10-14 days since your last risk, you can take one now.
