I think I may have an answer to this one for you. Having Lupus, you probably know that any change to someone's body can cause a flare, in different people they can be different changes. These can include weather changes, body changes (in weight etc) and even pregnancy. Your homones change totally when you are pregnant, and thankfully you went into remission! What I think may be happening with you is that your body is still trying to normalize after the pregnancy (I realize it has been 2 years though!). When you go onto the pill, it will try and play around with your hormones, and perhaps coming off of it was what put you into remission, along with being pregnant. After being pregnant, your body may not like the fact that your trying to give it a foreign drug again, and is rebelling by making you flare. You could try some low dose birth control pills or if these don't work then maybe it isn't worth playing with if its sending you into flares. I can't take the pill because of the havoc it causes with my Lupus. I hope this helps!!
