About three/four days ago I finished my period and two days after (yesterday) I started to carry on taking my contraceptive pill.
The same day(yesterday) I had protetcted sex, but before hand
He had ejaculate twice,is there anyway possible I could get/Be pregnant
As I had sex on the first day of my pill?

Have you regularly and faithfully been taking the pill in the months before this, or was this your first day ever taking the pill?

Yes the pill I take, is the concecative 3 month pill

No pill and no form of birth control is 100 percent. Were you also using a condom ?

But yes of course you can get pregnant, there is lower chances but there is always some chance.
