I used Loestrin Fe with great success. It is low estrogen.
I am currently using the Minipill - it is NO estrogen, but also has to be taken with more accuracy due to the lower hormones. I like it fine, but the only reason I am using it is it is the only BCP that is breastfeeding-friendly. When I stop breastfeeding, I will likely go back to Loestrin Fe.
