VVVVVFL! period 11 days late

Alyssa • Mother of 6 year old boy and pregnant with #2

I’m going crazy my period is 11 days late which is really unusual for me. Took a test and I don’t see anything though. Probably will try a pink dye with FMU but at this point I feel like I’m just wasting my money 😓 but my mind is boggled as to why I’m 11 days late. What do you ladies think?
