Negative Test but no period

Hey Everyone,

My Husband and I have been trying to get pregnant for 5 month now, no luck so far.

I was supposed to get my period today but so far nothing. I did a test this afternoon but it was negative.

I have a little mixed feelings.

I have light pulling in my uterus but that stops sometimes. Usually when I get my period it would get stronger and not stop. Also I felt yesterday nauseous most of the day, and had constipation.

Today I’m really gassy what I’m usually before my Period.

Also might sounds weird but my dog has been very protective of me the last 2 days, like he know something changed.

I don’t know if I start to imagine symptoms because I really want this so badly.

Any suggestions or help, tips.

Thank you
