I had my period on the 4th of January (a week late). It started off for the first two days with light/spotting then light. Not enough to fill a pad for two days before going back to the spotting for two days... My boobs were itching and sore (which I never have) and my nipples have been hurting since a week after af... Even having sort of cramp/gas feeling in lower stomach. Been ttc with fiancé for around 3 months... What's going on with my body? :/ also been feeling sickly on and off but not sure if that's to do with my fibromyalgia..
