Almost forgot i also had sex a day before my period started which was Dec 24 it came early . It was suppose to start on Dec 26 . I've recently had sex during the ending of my period. I been trying for 4 1/2 years very longgggggggg omg . Any way late Sunday my period ended but the glow calendar say today it ends . Getting to the point how possible is it for pregnancy. My ovulation day is tomorrow.
