Hi, welcome to HCM, I am Dr. Das.
No, there is theoretically no chance of getting pregnant.
As you took unwanted 72 it totally disorganized you hormonal
levels. You know, that the period is a total effect of decreased estrogen
and increased progesterone
. As unwanted 72 contains estrogen derivatives it delays your periods. So dont worry, its just hormonal side effects.
But if you get much tensed, just go for a pregcolor card test which will confirm you that you did not get pregnant.
