I guess its the type of thing where you aren't going to know until you stop taking the pill. If you think that is what is making you feel that way, then definitely stop taking it and see if that helps, but if you do DTD, then it will be best to use other methods to stop you getting pg until you are ready because while you are BF a lot, it may not be enough to stop getting pg kwim? It will also help you understand your cycle again as well.
