ok thats a really weird title isnt it

we are looking at ttc#2 next yr, its been 6weeks since giving birth to our first son, and i have no sign of AF yet, but was wondering if i can take the pill or do i need to wait til AF comes back??

Also during the time it takes for AF to return to take the pill can i get pg??
should we look at other contraception methods? or just not worry about it as we are ttc'ing #2 so soon??

TIA
