I get the evil aunt 3 weeks apart. Have done ever since my first bubba. Prior to that it was all over the place. It came back straight away after I had Angie and CJ was concieved mighty quickly despite me exlusively bfing at the time. There is only 11 months difference between them. If its anything like mine then you should be nice and fertile! Look out for the signs and go for it.

Good luck!
