Need advice

Hi, I was wondering if this has happened to anyone.

I have had a strange month.... I got my period pretty early, this also happened last month, so I just assumed it was normal and that it was my body changing. But then I got what I thought to be a period about a week later. Both were fairly light, no cramps like usual. The second go round was so light that it felt uncomfortable for a tampon, but would leave tiny spots on my underwear. The only thing I remember was just feeling tired all of the time. I have still noticed up to this morning that when I wipe it is super light pink and not a lot. I’ve never experienced this, so I’m unsure what’s going on.

Other symptoms: lingering headache for over a week, strange flutter type feelings in stomach, mix of constipation/diarrhea like every other day, breasts feels bigger, some dizziness, and of course fatigue.

I took a hcg test today, and it came back negative.
