Shawna
Alright, my period comes right on schedule every month it has for 6 months now. So this week I'm ovulating well yesterday I had light red spotting not enough for a tampon just a liner and we have had unprotected sex he has not pulled out could it be implantation bleeding but it also has lasted two days not just one????? I need help!!!!
