I have a dark line going down the stomach
The one you get when you're
pregnant
But I'm not pregnant
Last sex on 9th Feb
I've had 5 periods since then on time
And all
beta hcg tests have been negative
Less than 2 iu/l
Tests taken throughout March April may June
And all negative
And even had periods for month of feb March April may June
July not yet due
What might be the cause of the dark line
