I had sex last night and next day I had my period still for the safety measure I took I pill but now I am experiencing abnormal periods like start and stop. Can anyone help me out with a suggestion that what is going on inside my body and am I away from being pregnant? Please help me out, as I am very much scared

As you know, from reading the directions or talking to the store where you purchased. The pill has many side effects. One of them will have (or could have) effects on your next month cycle. And of course it is not 100 percent effective.

If you were due for your period the next day, and since you also took ipill, pregnancy would be very unlikely. You wouldn't be able to tell this soon anyway. As Fr_Chuck said, having off bleeding after using emergency contraception is common.
