Hi there,some pregnancy tests work up to 4 days before your expected period~go and try one of them.I don't think you could be but than again you never know.
Try one of them to ease your worries.They usally come in a 2 pack so you
can do one and in a few days another.
If you donot want to have a baby it is good you stopped but next time use protection!!!!!!
But iam sure you already realize that.
Let us know what you find or do.
Is this the 1st time for unprotected sex?
And if not was your last period normal?
Ooh if these symptms keep up and you've done a pregnancy test and it is neg.I would go to se your doctor!!
