Please help me out!!!

I was supposed to start my period on the 20th. My last period was 22nd-25th of last month. I had protected sex on the 29th but the condom broke. So as soon as we found out I took Take Action morning after pill. 2 days later on the 2nd I started to bleed for 2 days then it stopped. I've taken so many test and all have came out negative... Am I testing at the wrong time? This morning I tested at 4:50am.....could I still be pregnant or am I just freaking out here....
