Could Vaginal Spotting And Bloating Be Signs Of Pregnancy?

My friend has a 25 day cycle, was two days late this month. She started brown spotting on the first day, light bleeding the second days and passed some dark red clots (mostly small ones with one big one). She still bloated though complaining about that she might be pregnant. She constantly feels wet when she checks her pad, she only sees drops of blood with some tiny clots when she wipes. She is seeing her doctor soon, but she is very confused. When she stands, she feels something it's coming out like a period flow (like thick mucus flowing out), but she checks her pad only sees some spotting.. Can she be preg?
