Need some help am not very aware of all the ovulation stuff a bit naive unfortunately.

I had sex around 2 weeks unprotected  and today i started getting thick egg white like cervical mucus that had bits off brown and pink tinge through it and a bit of blood. With some pain on my lower stomach.

I've recently swapped from the implant to the pill and haven't really experienced having periods on a monthly basis.

Am i starting my period or could this be spotting and the early sign of pregnancy?

A bit nervous and scared any advice would be great
