Advice

Jessica
AF is a day late!!! Went to the bathroom CM was thick and yellowish. Super super sleepy even though I slept 8 hours. Took a test yesterday got a BFN. Today no cramping but my breasts are super tender and my nipples so sore. Should I test again? Or Wait it out? Today I felt so ridiculously nauseous I am afraid of puking at work and also had some heartburn. Any advice??? 
Thank you in Advance!
