hello there, i just want to ask if my GF was pregnant or not, she had her period on january 10, then it ends by 14, then we had this almost sex on 15, and maybe a week after, she had this brown spotting in her for just almost 2 days, and then it stops, nothing change in her body, but im still confused what was the spotting means, could it be implantation bleeding?(hope it's not). the spotting stops until yesterday, a red spotting and turns into brown and now it stops again. . does it means that she is pregnant?
