Advice needed! :-)

Hi everyone! I'm need of some advice, about two days ago I woke up at 4 am to feed my son, I went pee and noticed I was bleeding a little. I thought it was my perioid, because it was supposed to start that day so I put a tampon in and I went back to bed. I woke up at 9, went to change my tamp and there was nothing on it. So I'm almost 100% positive I was spotting, which is freaking me out because the last time I was spotting, I was pregnant with my son! My boyfriend and I do not use any sort of protection, just pull out method so my chances of being pregnant are pretty high. I took a test today and it was negative, I'm kind of confused if I should wait another week to take another or if I'm just freaking out and being paranoid for no reason? lol I know this is long so if you take the time read this, TIA.
