TTC and started taking prenatals

So me and my Husband have decided to finally start TTC we stopped using condoms in 2010 because we just didn't want to anymore not because we were trying we just didn't like the feel of them I have had 2 miscarriages since then pretty spaced apart my last one being Nov 2013 ....but we finally talked about it and we both are for actually trying! And I mean the tracking and for more BDing :) !!! But I started taking prenatals and omg sorry for tmi but have been soooo backed up and I know its because of them but what can I do to make it not so bad....do I stop taking them? I would rather not but I don't know if its bad to go as long as I have without movement?! What so you girls think? I also have Ovarian Cysts that come and go and also for the amount of time me and my husband didn't use a condom we did no tracking and our sex was very random and I do have irregular periods so please if you could refrain from any negative comments I would appreciate it :)
