12 year old daughter please help

Terri
My 12 year old daughter started her 1st period April 8th and then I got mine April 12th. She has had her period 2 times since then 😐😐 and me I still haven't gotten mine. I took 5 test already they all where BFN and then I tested for ovulation and got a positive ovulation test and EWCM. I'm just confused on how my daughter didn't Trigger my period yet if I'm not pregnant. Also I've been taking conceive easy by fertibella, do you guys think that is delaying my period as well. Please help.
