Could I be pregnant?

My usual cycle is 28 days at the latest 30 but very rarely. It's been 48 days since my last period. I took a test two days ago and it was negative but I've read and the say that could be too early to tell. If I don't have it in another week I will take another test. My husband and I aren't trying we use condoms cause I have had problems with birth control. I know condoms can break but I'm kind of nervous. I would love to have a baby he just hint ready yet. Any thoughts would be great. I'm having all the pregnancy symptoms but most of those are the same as period symptoms so it's hard to tell.
