Last October 21 was the first day of her period. She was regular since January. Then 6 days later, Oct 27 we're sitting and did mutual masturbation and i am naked but she's not. She has clothes but my hand was inserted from her belly down to her vagina so there is some space or way that the semen might have went on to her vagina when I squirted semen due to ejaculation. But i did not ejaculate directly into it. Then last October 30 I fingered her and i have my clothes on. Then later on she put her clothes on then masturbated me and I ejaculated. minutes later we did dry humping fully clothed but i didn’t ejaculate but there is pre cum. Then last November 7 she started to have brown discharge that last for about 3 days, and she said there's many blood. Until now, Nov 25 and she hasn't got her period. Could she be pregnant?
