Implantation?! Please Help!! Bare with me!

We have been trying conceive for a while, I have very regular periods so, I ovulated around the 18th, and then this past Wednesday-Friday I had VERY light bleeding. Which was 10 days before my period. (I’ve never spotted between periods)

I only noticed when I would wipe. The colors ranged from brown to faint pink. No liners even needed.

I took a test this morning; Negative.

Tonight around 7:00pm I used the bathroom, wiped, and light bleeding again!

I haven’t had cramps, breast tenderness. Just frequent urinating, fatigue, and headaches. (But it could be allergies) please help, I’m so hopeful but I’m nervous. I’ve had one miscarriage as is. Please help!
