I got my period last week a day late which isn’t a big deal except it was super heavy that first day-heavier then normal. The next 3 days were so light I barely needed a pad or anything. My periods last 6 days not 4. So that was weird already. I’ve been having terrible cramps since the week before I got my period and my period is now over and still having these cramps. Took a pregnancy test and it was negative. I’ve been exhausted lately even when all I’m doing is sleeping I’ve been having back pain and headaches for no reasons..: can I be pregnant? Has anyone had a similar experience? I need to figure this out as soon as possible
