I got my af back when DS was 8mths old and was BF at least 6times a day and my cycles were generally pretty even but I got some weird ones too (longer and shorter, lighter adn heavier). i think I ended up doing 4-5 HPT as I was sure I was pg. i got those phantom kicks too and have heard lots of previous pg women wonder if they are pg because they get them too, they feel so real don't they.

I guess the only way to know is to wait a few more days and test again. Hope you get some answers soon.
