Really confused?!

Amber
Me and my husband have been ttc for almost a year now and no luck well my periods are always on time besides last month I was hoping I was pregnant cause I was 5 days late well that was a no and now it's the next month and I'm 6 days late took a test at like 11:30am and it was a neg so it's really weird how my periods are being off and this time I wasn't paying attention or stressing myself out on if I'm pregnant or not. Anyone else experience something like this?
