So my period was really weird this month. I had several days of spotting then halfway through Saturday I got bad cramps and heavy flow (tampon change every few hours). Then Sunday morning it was a lot lighter (used one tampon in the morning and then didn't need one the rest of the day) spotted slightly on Monday and today basically nothing. So only 24 hours of actual flow. I really don't feel pregnant but that is a super short period for me. Should I waste the money on a test?
