EBF & minipill

I am 4 weeks pp, breastfeeding my LO on demand, and have been on Heather (mini pill) for nearly 2 weeks now.  Last night my husband did not pull out. I'm looking for some reassurance, lol.
Also, side note, anyone else take Heather (or another mini pill brand) and like it? Dislike it? Effect on milk supply?
