I Was Getting Naughty With My Gf, I Didnt Penetrate

i was getting naughty with my gf, i didnt penetrate her but was masturbating near her ass but few cm away from her vigina, we are both virgins and she assured me that she didn't felt any penetration and when i ejaculated, i did it on a piece of tissue, plus she has irregular period , we were still scared so she took the contraception pill (ellaone) on the second day , will she still get pregnant ? the gynecologist says its very unlikely but today is only the third day and i have to wait till the 30/1 to test with the pregnancy test and im very anxious help.
