period, spotting, implantation, anything

so I started a light spotting two days ago and it was dark brownish with some clots. I thought it could be implantation bleeding, but it's here for the third day and it's slightly heavier, although not as heavy as my usual period. it's a lighter colour but still more brown than red.

Period is now due in six days and I'm not very regular, I went off the pill in March, but cycles have been longer than shorter.

I had some extremely stressful events last week and I'd been trying to conceive before. I had a positibve ovulation test on June 4th, about ten days ago.

I'm going crazy. Has my period decided to randomly show up, is it implantation bleeding, am I having an early miscarriage?

What the heck, vagina?! 😐
