Yes they are a sign of pregnancy, they kinda look like little pimples ??? I would do a HPT in another week, goodluck!!!
No, you woukd not have pregnancy symptoms yet. You can test two weeks after unprotected sex which is about the time HCG will start building up in your system.
it usually takes a few weeks for symptoms to set in but that would not be the only symptom if you were, wait a few weeks and see
