Can I be pregnant? Without more information it is difficult to give you an accurate answer. One needs to know how and when your periods are, when in relation to your normal period history you were exposed to semen and sperm. This scenario you are describing could represent some irritation and/or damage with deep sexual intercourse with penetration. If you period is late then it would be time to get a hpt.
