I'm getting nervous. Me and my boyfriend had protected sex (condom, didn't break or leak out) like 3 weeks ago. On the day after of I was supposed to get my period I took a pregnency test and it said negative. On that same day I went to the hospital for having a "blockage" and have been on an all fiber diet since. I keep feeling like I'm going to get my period but I don't. My boyfriend freaked me out because I said how I think my breasts are getting bigger because I gained some weight but his first reaction was I'm pregnant. Could because of the blockage I'm not getting my period?

Very likely it is the other issues, but of course as we always remind people, condoms are far from 100 percent effective so if that is the only protection you are using, yes you can be pregnant.
