I have been on Loestrin 24 Fe for a couple of weeks now and just had a baby 7 weeks ago. The beginning of this week, I had severe nausea and was unable to eat without becoming nauseous. I believe it is due to the pill and not the food I am eating. Today, I have had breakthrough bleeding that is heavy like a period and severe stomach pains in my lower left abdomen. I am going to call my doctor tomorrow if they don't subside. It is really disturbing that before I had the baby, I had a yeast infection on my skin while on Desogen, so I quit birth control all together. I was hoping that after having the baby, taking a low dose birth control would be okay...but I am a bit worried about the stomach pains. I am not so worried about the break through bleeding because I know it is normal. I have also started to get acne on my upper arms and not my face...totally weird spot for me. I have had dry, itchy skin also... especially on my face. Please respond if you are having similar pains in your stomach.
