False negative tests??

Has anyone ever been pregnant and had negative tests before?...

I had a baby last november and ctcle came back pretty soon after in January and I was getting fairly regular cycles then they had just sorta went bonkers...spotting and weird discharge..then they just stopped. I haven't had one in 92 days now but just recently started have cramps and very bloated. I look like I did when I was 7 months with my last baby but all my tests say negative.

So any insight or similar situations would be very helpful.

I am planning on seeing my dr as soon as i can.
