Hello, I am 36 yrs old, Asian with fibroids they has been monitored over the past 2 years with no change in the size. I am on a 21 day birth control pill and my periods come on time. My last period lasted a normal length ( start date July 29 and end date August 7). On august 7th I began taking an oral typhoid vaccine for an upcoming trip. I took the pills on alternate days (August 7,9,11, and 13). On the 12th of august I began noticing a light discharge. Each day up to today I have noticed an increase in blood flow (using a feminine cup that was filled only about 1 tsp per day.) sometimes there are clots. No cramping or nausea. This is the first time I ve experienced this breakthrough bleeding for as long as this is lasting. Is it possible that the typhoid vaccine could be a factor? Also I used to eat a low carb diet for the past 2 years and my diet is significantly different. Any advice would b great.
