CURIOUS/ maybe tmi

So I’m late on my period by 24 days.

I took a pregnancy test 3 days after I was late - came back negative, me and my fiancé have unprotected sex all the time and haven’t stopped since I’ve been late.

Seeing that I have waited a couple weeks, should I test again???

I’ve been cramping and have had sore nipples for the past week. But no period or anything. I normally can call when I’m about to start my period, I’m really emotional.

I’m not emotional though.

Just sore nipples and a late period

SOMEONE HELP PLEASE!

Could it be just my body changing?

REALLY WOULD LOVE SOME ANSWERS HERE ON WHAT TO DO!!! AND WHAT YOU GUYS THINK
