Week late. Brown blood.

My period usually is only ever late by a day, except for when I found out I was pregnant with my son. Now my period started but it's extremely light. And just brown. Usually, it's like pouring a bucket of cherry pie filling. Last pregnancy I spotted bright red and dirtied one pad. This time, 4 preg tests deep during me first noticing I'm late. All negative. The only thing is first pregnancy I found out at 5 weeks, and confirmed at 6 weeks by a clinic. I didn't keep track of my periods and swear I thought I had mine that time and feel it doesn't line up. Anyways, I've kept track religiously and I'm having some other strong symptoms.

Super sense of smell.

Acne.

Sharp cramping.

Super sore breasts.
