Advice please! AF 3 days late and confused!

May

Hi! So my period is now 3 days late and i have had 3 negative results ( 5days before, 4days before and on the day of expected period- as it was Christmas I had to make sure whether it was ok to have a drink- please don’t judge)

I am usually pretty regular except last month when I came on a day early after sex but it was light up to the 3rd day and lasted 6 days instead of the usually 5 days.

After my fertility window mid dec (bd only twice) I had a feel dull cramps a few weeks before my AF was due and was a bit stronger but on/off after the first day of missed period. On/off sensitivity to smell, slight nausea and sensitive to smell (not regular), lethargic..

Just started experiencing sore nipples and lots of night pees (sorry tmi).

Not really experiencing the usual AF symptoms- breakouts, sciatica now the leg .. etc

Sorry for the long posts.. we have been ttc since October so advice will be grateful as I don’t really want to speak to family or friends in case I am being silly!
