I had my first baby at the end of Jan this year, so he's now 9 months.
HOWEVER
Over the last month or so, I've developed what looks like a small pregnancy bump (it's definitely not weight gain - it's firm and low) and I've noticed I'm urinating more often, dreaming really vividly every night, feeling especially tired, having lower back ache and occasional waves of nausea. I was a day late for my period, but it did eventually come (a little lighter than usual). I've taken several different pregnancy tests and they're all saying negative.
What's going on?!
