Baby time? or is pms just on hold?

Been trying for 3 months to have a baby. So far it hasn't worked but lately I have been eating ALOT more than normal and have occasional small abdominal pains I guess you could say... Also, My period is a week late, and we do it everyday lol so yeah. Could I be pregnant or no? I have no way of being able to tell at the moment because I have no way to get to the store or the doctor to find out.
