Advice! Please!

Hi all! AF was supposed to visit me this morning and it never fails I start early in the morning well this morning I haven't seen it yet. Which is definitely weird I haven't started thinking about it until just about an hour ago. I'm not stressed at all at least I do not think I am. I'll wait it out until tomorrow to take a test but I totally do not feel any symptoms. Just the usual cramps earlier this morning which were horrible and one of the days after ovulation.  But I guess my question is that if I could be pregnant if my usual time of day to start is early morning?? This would be my second pregnancy and with my first child I didn't experience any of this I just had the implantation bleeding and that was it no symptoms throughout my whole entire pregnancy.
