I have been having unprotected sex once a week for the past one month,took p2 twice a few days apart and i've experienced cramps daily. my period is late but there has been some spotting, could i be pregnant??

Maybe: Pregnancy is a common cause of a missed period (home urine tests are accurate). In a woman with regular periods, other causes of a late period include: excessive weight loss or gain, increased exercising, emotional stress, having an illness, traveling, medicines (like Emerg. Contra. pills), hormonal imbalances, etc. Seeing a doctor is a good idea if symptoms are persistent, recurring or worrisome.
