So my cycles average 36 days. According to some apps I would have ovulated on Nov 6-7. I had sex then. Day before yesterday I had pressure. Yestersay I had cramping and today I had 3 tiny spots of light pink blood then it stopped but I have a lot of discharge. I'm due to start on the 21st. Could it be just implanting or ?? Cause I never cramp before a period or have any discharge
