Implantation

Lauren

No idea if this is the right group to post but anyway, I had sex on my ovulation day and since about 4 dpo I’ve had headaches sore boobs and back ache and just feeling off, since last night when I wipe from the toilet I have the tiniest bit of red blood like really small, and kinda like discharge mixed with slight blood as it’s an off colour, sorry tmi, could this Be implantation bleeding, I never had it with my first but my period isn’t due for 3 days, has anyone ever had tiny amount of red blood mixed with discharge when they wipe and it ended up being implantation bleeding?
