5 days late and negative test


I’m super confused. I’ve always been regular but this month I’m 5 days late and just got a negative test. My period was right on time when i went off birth control two years ago now, it was right on time when i had a miscarriage in December, i don’t understand why my periods messed up now. Help!

I’m not stressed out at all, this is the most chill I’ve been with ttc in the last two years. There’s no reason i can think of other than pregnancy to be late.
