My last period was Feb6-Feb12. Me and my husband are pretty sexually active. We use the "pull out method" i was expecting my period on March6-March12 but on the 7 i got very light pink spotting whenever i wipe only. Its been like that these past two days. but my period is usually heavy or really bright red. Ive been having cramping and back pains and been feeling different/strange. Ive tested Monday but came back negative. I don't know what to do anyone have any tips??? Please help me out. Thanks in advance.
