I’m currently 4 days late. I haven’t tested since before my expected period date my period is never any more than a 31 day cycle, (currently 34) I’ve had nausea this morning my boobs are vainly and swollen I was so convinced I was pregnant until I wiped today and seen this. Normally I get really heavy periods to start but this seems to light. Dose anyone think this is something els or is it my period starting.
