Hi, i urgently need help pls...

my last periods started on 7th Dec. on 14th Dec had sex but took 2 pills of microgynon 30 on the next day just to be on the safe side....

The next night i took another pill and stopped since i knew my man was going to be away.

He came back on 27th and we had sex again but i didnt take any pill as i knew am on safe days.

Could i be pregnant or my periods are just delayed?
