Vaginas symptoms and conditions

Few days ago I posted how awful I felt ....an extreme tiredness and generally feeling rotton!Had a good cry too!Well today I have my period well brown smelly(sorry Girls)discharge.Im presuming its my period ...I don't really know as I get spotting on and off and don't make note of the dates.Im thinking its only been 3 weeks since my last though!!!Im in good form now although still feel bloated.Im presuming it was pmt I had??????
Ive never suffered with that before ,even when on the pill for 8 years.
I was 100% getting it removed earlier this week but now Im thinking Ill keep a diary and after a couple of months decide.....
Although...gut instinct ....get it out!!
Now Im thinking why has this discharge got an odour....I don't have symptoms of thrush...and I have only one sexual partner,my husband!Gee....im still confused...yes confusion might be another side effect....Oh NO!!!!
