Any ever experienced this?

Okay ladies. My period is always on time and I check my cervix each cycle and this cycle I haven’t really had any pms and my cervix is high and soft. I was supposed to get my period today and haven’t. No signs of it happening cervix is higher today and softer I just took two test to see at lunch and both are negative. Could I possibly be pregnant or should I just assume my period is going to start? Like I said my period is always on time and I’ve never had a irregular cycle
