Am I pregnant? please answer?

On May 10th & 20th I had sex with my boyfriend & the condom broke. On May 22 I had some slight spotting. May 23rd it was a heavier flow. It was very light though & brownish in color. It lasted til May 25th or 26th. I'm very worried. Was this my period. According to the dates if it was my period I should've had my next one on the 20th. But there's nothing. I've been having cramps since the 19th they were very light at first but now they are very painful & only last about 30 seconds. I took 2 pregnancy test, they were both negative. I took one a week after the last one broke & one 2 weeks later. I feel like I'm on my period as if the bloods gushing out but it's just white discharge, & sometimes it's nothing. I've never rkep track of my periods til nos so I don't know if I'm irregular or not. So my question is am I pregnant? Or am I just stressing too much?
