So my calender says its coming in 4 days i been spotting for about a week i never feel it so it frustrates me cuz i think itll stop nd its pinkish brownish idk whats up with that, but ive been thinking alot of trying tampons for first time ive read lots of girl prefer it? So i wanna see if i like it better. What are ur thoughts about it nd why do most girl prefer it? Will i feel uncomfortable or? Pls share ur thoughts thank u!(:
