Is she possibly Pregnant?

Dajah 💁
Okay my friend , and yes this is my friends situation and not mine is currently dating a guy who mentions constantly that he wants to get her pregnant. We're all still in highschool and I personally think he is really trying to. She tells me they have sex often and about a week ago she mentioned she was spotting three days after they had sex and now her period is like 2 days late. Could she be pregnant? Just worried for her 😕😩
