Stopped pill breakthru bleed and vitex ?

 Hi I am curious to know if anyone knows anything about this . I have been on the pill for 2 years now . recently I  started to forget to take them a couple times and actually thought I had. When I went to take one I realized I hadnt taken them in several days . ( I have extremely bad memory ) My husband and I were planning to stop and ttc the following month  anyway so i went ahead and discontinued them . As I had pretty much already missed a week.. Ok so 9 days later I had a withdraw bleed?? That lasted for only 3 days but was heavy and normal . I decided to start taking vitex in hopes that this was a actual period and maybe my next one wouldnt show up during our family vacation , before or after would be fine just obviously wouldnt want it during lol. Anyway Im really confused if I may already be preg then I shouldnt take the vitex but, Im not sure when I would have ovulated or if even at all I did have several days worth of pain which i assumed was ovulation pain as It was similar to the ones I have had in the past ..  I have no idea when i shold expect a next period .If I should be going by the one my pill had me scheduled on or if I should be going by the one that lasted only 3 days  . On the actual date I would have had one had I still been taking my pill I woke up went pee and had a light tinted pink discharge but nothing since and this is into the following week now. Over the weekend I also had a thick white discharge . I dont wanna test yet as I was planning to wait until the first of  next month going only by my 3 dAY BLEED.  If you have any insight at all I would greatly appreciate it and sorry if I have confused anyone this is really confusing to me ...  thank you
