Can I be so far along that a pregnancy test would be negative?

For the past 6 days I've felt a lot of movement in my lower abdomen, looking at my calendar my cycle has been irregular but haven't missed one, my last one was light(lasted 4 days) and I'm trying to remember if it's been like that for a while...I took a test in the middle of the day and it was negative...My BMs have been normal, and I have two kids before so I know what I'm feeling...obviously I haven't been abstinent but we have been using condoms...hmmm just feeling like if I'm not pregnant I'm losing my mind, and also wondering if I was far enough to feel movement if a home test would still show up as positive....thanks for input!
