YES! I was on it for several months from 6 wks after my first was born. It ended up being the sole cause of my PPD. I went off of it after several months to see if that was the cause as I had had problems before with the combo birth control pill. Within the first month I could feel my head clearing and started feeling so much better and in control of my life again. By the second month I was 100% back to my normal self again. I made no other changes besides going off the mini-pill. My friend is a registered nurse and told me that progesterone is a depressant. It is the hormone in the mini-pill. Some women react badly to it, myself being one of those. She is the one that suggested I try going off the pill when I was having my issues before I tried taking the Zoloft my OB had prescribed. When I mentioned to my OB that my friend suggested it might be the mini-pill she brushed me off rather rudely with a "Yeah, it might be that and you can try going off them if you really want to but take this prescription anyway." I never took any of the Zoloft and was happy as can be!
I had 2 other children afterwards and skipped going on any hormones at all and did not have PPD or any other issues with depression at all.
If you already have a history of mental health issues I would strongly reconsider your choice.
I wish you the best!
Edit: There are other options for birth control while breast feeding besides the mini-pill and condoms. You can use the copper IUD which has no hormones in it or you can use a diaphram or even Natural Family Planning. Jill F. is incorrect in her statement. If you plan to breastfeed longer than "just a few months to a year" (WHO recomends 2 years or longer if desired by mama and baby), I've nursed all of mine longer than " a few months to a year".
