Hey ladies

Okay so here's what's been happening, OD was around the 5th-6th of June. I started spotting pinkish reddish on the 9th and it's still continuing, not enough for a liner but just when I wipe.

Been having back pain, nausea, dizzines, headache, and some pressure in my lower abdomen.

I've taken 2 different brand tests both negative, af due June 20.

I know I'm not out til af shows it this spotting has me a little worried.. I read somewhere that women can have a slight period even when pregnant but can anyone give me some advice?
