I had a period December 22 and then another one January 8th, i haven t had a period and took two pregnancy tests and they were both negative. Back on the 1-2 of February i had very little spotting and have been cramping on and off since then. During the last two days my breast are a little tender, kinda like when working out too much. Could I be pregnant or should i just ignore this and wait for my period to come?
