i started my period on the 29th of october and calculated my ovulation from abt the 12-17 of november. we had intercourse for the first time in a three month break on the 16th ofnovember and i had dark brown spotting with a light pinkish discharge around it two days later. i continued to have light spotting for a couple days then a 24hr pause and i bled lightly and red for the next couple days and then it ended. my nipples are extremely tender and i have beee pretty emotional... is it possible to have conceived in that immediate time frame even though implantation is supposed to occur 6-12 days after intercourse? help!
