No PMS this month? Wait what?

I know it’s a good thing to not have a pms but this is just very unusual for me. I usually get pms a week before my period and it’s already 4 days before my period, i haven’t been getting any symptoms such as tender/swollen breast, light headedness ,nausea and cramps... i just literally noticed it today! My bf and I have been ttc for baby #1 and still no luck. Also, last Nov. 1 i had a spotting 4 days after my 6 days period last month and i had sex with my bf right after i was off of my period. Could there be a possibility I am pregnant?
