Need help please

Amanda
Ok I need advice, please. on aug23 2014 I gave birth to my son via c section and who passed sept6 2014 it's now oct 2015 and been ttc this whole time according to my chart I ovulate about the 16th of oct my period ended the 2nd but today (the 6th) I have been having a white mucus and a lot of it what is going on I'm cramping, light headed, dizzy, and sore breast I had intercourse the day before my period (sept 27) which did come and last 4 days so I don't think it's due to prego but no clue what is going on? Could I be ovulating early? No negativity please really just need thoughts, still not sure how to tell 100% the signs of my body yet. 
Oh also I was on nexaplon till jan 1st so I know my hormones were off but could they still be? My home nurse thought it should all be flushed out was only in 3 months and have had it before and removed only took 2 weeks to conceive. Any help or thoughts greatly appreciated.
Thank you!
