preg or not

Ellie
Last month me and my bf got down and the condom broke so I took emer contra right an hour later. 5 days later I started ovulation and had a bit of spotting. My period was a week late but was kinda normal. Normally I don't have any pain either when ovulating or on period, but recently I been constantly having mild abdominal pain mostly on the left, sometimes left side back pain which spreads down my left leg. I tested this morning and this turned out, but I'm still worried if there is a possibility that Im preg. Help!
