as i was standing in line at kroger today , i had a bad hot flash and some nausea . this has happened a few times this month, now ive had heart burn for a few hours .. also last week i had weird cramping for a few hours then theyve not came back (it was around my pridicted ovulation date) i have pcos (&ttc;) but have never had or heard of these being symptoms.. anyone experience this before ? and if so what was the deal?
