Help!!!

Hey ladies this is my calendar results for this month now i have a really irregular period and found out i have PCOS so that plays a huge part. Ive been on metformin since the last week or so of last month. My last 7DC was in September i got a 4DC this month (NOV) along with an 8DC which i only started spotting after my pap smear and didnt stop for 8days same as before; spotting only there when i wipe and wasnt constant and didnt start getting heavy till around day 3 till day 7 even then it was hardly noticable. Enough to get on a tampon but not soak it.. Was there by looking at the calendar any chance of me falling pregnant. The 4DC was light spotting only noticeable when i wiped and came and went that whole 4 days. I had sharp pains in my left side that shot down to my leg a few times. I was cramping the last 2 days but all of a sudden no cramping and i feel fine except that im hungry all the time. Ive had horrible Nausea, havnt been able to sleep, hot flushes, indigestion/reflux or heartburn cant figure out which one it is, constipated, loss of appetite all of a sudden then it increased and i mean... ive been craving alot!!!, hardly any sex drive even though we BD every night, my CM went from thick creamy to watery then last night i noticed it was like clear transparent slimy stuff. And now its creamy again this morning. Im so confused, its doing my head in trying to figure it out. Any advice?!?!(learn more on Glow: https://glowing.com)
