Implantation Bleeding With Clothing Implantation Bleeding Or Period?

Implantation bleeding or period? - implantation bleeding with clothing

Can you dry clothes pregnant fuck, for example, if you think the man has sperm near the vagina? Clarify (To improve things - never have sex), and if so, does the implantation bleeding seem like a period and have the same symptoms begin before the expiration of a period, for example, very bad cramps, back pain and the fact look the same and so long? Implantation bleeding is dark red? Because if possible, I can not say if it was my time of pregnancy or small chance that the semen somehow close to the vagina and effectively on his way. As far as the semen is to be in the vagina or the extent to pregnancy?
THANK YOU!
