birth control
"I took Lo Loestrin Fe for 2 years and honestly loved it. I switched briefly to the generic version for a month, and it was freaking awful, so I switched back to Lo Lo right away. 
Only issue I encountered on it was that I ovulated over the BC.. which resulted in extreme breast tenderness & growth (for about 2-3 weeks) and weight gain. When this first happened to me I really thought I was pregnant, after a test came out negative I went to my OBGYN and she explained that it was too low a hormone level to properly regulate my cycle. Hence the ovulation. So then I switched to generic and ended up just switching back again. 
I finally stopped taking Lo Lo after the 2nd time I ovulated over the pills and got an IUD. 
Overall though, great BC"
