I have no idea what's going on.
I'm now 5 days late,
I took a test when on the day my period was due because I was so sure and it was negative (first response 45 second test)
Im pretty sure it has to of been wrong because well I'm sick everyday & I'm pretty certain having already had 2 kids that what I'm feeling is happening, when I'm lying down in bed I can already feel a hard bump around my pelvic bone In my mind I'm guessing I'm around 3-4 weeks but..
Why would my test be negative am I overthinking or should I test again? I'm waiting for this period but.. i don't think it's coming. 
(Should mention I've been feeling bedding in cramps too completely different from my usual period cramps I don't really get those until I'm actually on my period if that makes sense)
