Im not sure If this is considered Implantation.. or something else

that would be old blood from your period that your body is trying to get rid of. if you have a 28day cycle then you would ovulate on day 14 in your cycle with day 1 being the first day of your period. you can ovulate a day early or late so try to time your unprotected sex for around that time. and also try doggie because when he ejaculates it will plant the sperm right at the enterance to the cervix so the sperm does not have a long distance to travel. so do doggie then when you are done lay on your back for 20min and place a pillow under your butt. it will also aid in the sperms swimming. and try not to cough, sneeze or laugh because these 3 things can actually push the sperm back out. good luck and have lots os sex. :-)

Thank you very much for your answer and advice :-)

I have had my menstrual cycle twice in a 28-day period. What would cause this?
