32 days since last period

Kayla

I am currently late. My last period was January 23rd and has been coming early for the past few months so it was expected to start around the 18th of this month. I haven't gotten it yet but I have been having cramping in my lower abdomen and been very nauseous for about a week now. I keep taking pregnancy tests but they're all negative 😔 anyone know what could be going on? Been TTc for 6 months

*I had a positive ovulation test on February 4th.
