Need your thoughts on this?

My husband & I have been actively ttc for over 15 months now. As of yesterday I noticed I have been getting queasy, lightheaded, crampy bloated and my boobs are soooooo sore. My period is not til next monday though. I never experience symptoms before i start either. I took a test about an hr ago and it was negative ***i know its way too early to take one*** I also have been getting cramps in my leg which i havent had since my track days back in hs 4 yrs ago. I was just wondering if any of you have experienced this and received a BFP, and if you have done first response, how many days before your period did you get your bfp.. Our daughter will be 3 soon and just feel like this is the right time. Oh yea, lots of watery discharge the last few days as well. Ok, im done. just wanting some input!
