You can't get pregnant if you're still a virgin. The only way to get pregnant (other than fertility treatments) is to have vaginal intercourse with a man and if his sperm fertilizes your egg. That is the only way it can happen. If you're a virgin, you can't be pregnant.
by not consumating marriage - I mean I'm still a virgin - you may read my previous posts to understand
If you are using condoms and they have never come off or broken, then you can not be pregnant. As for what you said about consumating your marriage, I hate to tell you that anytime you have vaginal penetration by a penis, whether you are using a condom or not, you have consumated that relationship.
