AF 5 days late..

Marcie • Mommy to 2 beautiful girls! Pregnant with baby #3 💖💖💚
AF is 5 days late.. last tested Thursday and was BFN. Since Friday my breasts are sore and nipples are swollen.. going to test again tomorrow morning but this is getting so frustrating!! Cycle never regular... anyone going through something similar? Some support would be great!
