Nose drops?

So I've been using nasal decongestants daily for many years now and I've diagnosed myself with rhinitis medicamentosa but never got around seeing a doctor about it. I'm now 9 weeks pregnant for the first time and, from the moment I knew, I've cut back tremendously on the nose drops fearing they could harm the baby but I can only go without them for so long. I'm going all day without them no matter how congested I get, but when it's time to go to bed I have to use them. I have noticed that I'm getting less congested (maybe this is what I needed to quit the terrible habit) but I'm still using them if only once a day.
