there is no test uploaded under your name

your cycles are a bit short: with a 15-20 day cycle it is very very difficult to get pregnant:
note that normally the luteal phase should be around 13-15 days meaning that you ovulate during the very early days in your cycle: too short for the eggs to be ripe and for the uterine lining to be thick enough to host an egg.
so if you are thinking of ttc you should get an appointment with your doctor to extend the first phase.
