If you are 10 days late then yes, you could be pregnant, especially if you were sexually active around your ovulation time, typically 14 days post first day
of period. Early
signs of pregnancy can include cramping, and it is not uncommon for women to having spotting instead of a period during early pregnant, but those signs can also be caused by other things, like your period. At this point you cant just go by symptoms and instead wait it out and retest, especially since you havnt had a period.
