i just recently had a baby october 25 , 2015 .... me and my bf had inter course during my six weeks , no protection no nothing ... i recently had implantation bleeding .. then i recently started my cycle or i started a bright red LIGHT bleeding that doesnt look anything like a period  . remind yu the same exact thing happened in the same exact order with my daughter .. and with my daughter it took me 4/5 weeks after the simi bleeding to test positive for pregnancy .. now im wondering am i pregnant again ? but i just have to wait 4/5 weeks again until i should test?? i think im expecting  again cause my doctor says women are very very fertile during your six weeks ... has any one been thrh something similar?
