help please

I'm 24 and have PCOS I have a 4 ur old so I know I can have kids just a little more difficult.. I went with out a period for 9 almost 10 months when I found out I was Prego with my 4 ur old... but my current problem is.. the last two months have been spot on 28 day cycles because I was on progesterone or something like that u take for 10 days then have a period to reset my cycle will my first day's my last period was Oct 9th and If my body is doing a 28 day cycle I'm due for af on Nov 6 well I ovulated on Oct 23.we had sexy multiple times the days leading up to... on and following I started lightly spotting on the 30th and 31st. I had a Dr appointment on Nov 1st the Dr said with my other symptoms that the light pink spotting could be implantation bleeding or my body trying to start my period early... so I'm going to wait to see on the 6th but from my symptoms below does it seem I could actually be Prego this time? I've been dizzy and had light cramping off and on. I don't have much if an appetite but before af I always eat so much.. my moods are all over the place I'm so tired and I sometimes can feel like little hot flashes kinda and I'm sick protective of my belly with out noticing I'm doing itand I only want certain things to eat Dr said I look to be having a little extra blood flow down there and it happens before af sometimes and slot of ppl have that in early pregnancy... what do y'all think
