Should I test?

Rachel • Married to the best man on the planet! Texan born and raised. Currently expecting baby #1 after 5 years of trying!

I have 2 days until af according to Glow, however she does tend to have a mind of her own! My husband and I aren't officially trying but I'm not seeing any discoloration in my discharge (which is normal for me a few days before af). I don't know if this is just af being fashionably late or if I should test? My husband and I had unprotected sex last month on my peak ovulation day but there was no...."happy ending" for him (we don't want to conceive right now but if it happens it happens) as a precaution. I'm a little nervous on whether or not I should test. I've been really tired lately and have had sore breasts as well but not painfully sore. Any thoughts?? Any help/advice is appreciated!!
