I'm a 37 year old mother of two who is fortunate to work in an OB/GYN office and have different BC's at her disposal. In the last year or so, I've tried Yaz (only stayed on for a month or so and quit due to weight gain and fatigue), the NuvaRing (had yeast infections) and now have just finished my 1st pack of Loestrin 24 FE. I have had spotting all month (enough to use a light tampon), severe mood swings (like a want to tell people off in a bad way!), severe fatigue (want to sleep right as I get home and be a couch potato) and WEIGHT gain (which I HATE!). I am in great shape and wear a size 6-8 but now feel more comfortable in a size 8-10. I know that you should give any BC at least 3 months to work but I don't know if the pros outweigh the cons. Also I did noticed a decrease in sex drive and the drive to want to exercise. I feel horrible after I eat and and feel constantly bloated even when I wake up in the morning and haven't eaten yet. I'm on the fence about staying on this BC.
