The Pill

Ive been on birth control for about 2 weeks now, called Lessina. This is my first time. Ive experienced some really bad mood swings and cramps. Now lately when I use the bathroom there is discharge that does not smell or look like my usual. It’s not that really much of a bad smell, its kind of reddish at times. Im not sure if its spotting but i wanted to ask if any ladies can give me descriptions of their side effects on this birth control pill or any other, and if my symptoms are normal. Thanks!
