Fewer calories symptoms and conditions

I just finished my first month and so far I have no complaints. My period came regularly and lighter which was awesome! I have lost 4 lbs...however I am eating fewer calories so I don't know if the pill has anything to do with that. My sex drive is normal, actually I think my G spot increased in size if that's possible lol. So far so good. No stomach issues either. I guess every pill is different. I have been on 3 others and the one I don't recommend is ortho tri cyclin low. it was great for 6 months then made me have severe mood swings and spotting.
