Does this brown/dar red discharges look normal to you?

I am 8weeks pregnant.

It all started 4 days ago with some light brown discharge immediately after a bowl movement.

After that, for the following days, i noticed some small brown traces after wiping but nothing alarming.

Last evening I felt some sharp pains in my vagina, climbing up. I would say of moderate intensity and lasted for a couple of seconds. Before going to bed, i used the bathroom, wiped and noticed a small dark red/black dIscharge.

That disappeared and until morning i had just a little watery brown one that filled a bit a daily pad. No pains.

Today i can see some small brown/grey traces when i wipe.

Attached the pics in order. I am so afraid that this could be a start of misscarage. Not sure what to do. Thank you
