Should I be nervous or not yet?

Ashley

So as of today I am 2 days late. I did have sex on my ovulation day and a few other times around that time and throughout the month. I’ve been having lower back pain and some pelvic pain. Some smells have been bothering me more than normal, I’m hot all the time, today I’ve been feeling really nauseous. I do have pcos so my periods being irregular can be normal for me but for almost 2 years I’ve been regular. I took a day the first day of my missed period. But idk if that was too soon.

What do y’all think?
