TTC for 4 months now. My boobs normally hurt from ovulation day to the day my period arrives (I mean they swell double the size and hurt so so bad!) my periods always out by 2/3 days. But I'm 5 days late now (boobs don't hurt but are still swollen and firm) I took a test this morning which was negative... I'm honestly so confused? Can anyone help or give advice from experience? Thank you.
