(TMI PICTURE) can i be pregnant 2 weeks after sex

ella

2 weekends ago i had sex 4 times with my boyfriend. and only one time we didnt use condom but he pulled out.

I'm having really light brown spots since 12 hours ago. this is my cycle day 22, i usually have my period on my 30-35 day on the cycle.

could this be implantation bleeding?

this accours in about 12 hours, its morning here so i this all i got overnight.
