3 days late ....Advice PLEASE..update ...

Amber

So im three days late and usually I would have taken a hundred pregnancy test by now ! .. my last menstrual cycle was it normal for my 5 to 7 days, but then it was different I bled for another week I believe it's due to a cyst that has ruptured because I do have PCOS ... has anyone experienced anything like this ? Could I be pregnant or am I just late because of the cysts rupturing? Update... so now I am 5 days late took a test yesterday was negative... I'm gonna say the pcos is the cause of this but once agian if anyone can shed any light on what's going on with me, that would be great !!
