5 days late should I be concerned?

So back on March 3rd I had protected sex, he ended up finishing on my butt and I freaked out and took plan b (thinking it would make its way to my vagina). I bled for about 3 days a week after taking that pill. I had sex again on March 31st, he had a condom on and we stopped after three minutes and looked down to see that the condom broke. (I know it was three minutes exactly) he said he didn’t cum at all and he knows there was no pre cum. Either way, I again freaked out and took plan b. I was supposed to get my period on the 31st of March and I’m 5 days late. I took a pregnancy test test yesterday and it came back negative. Please help me and give me some advice. I understand the consequences of having sex and I’m going to an obyn to talk about birth control next week so I don’t need to hear that. Please help.
