Re: Regarding Morning After Pill
As long as you nurse on demand, your baby should be able to get your supply back to where he needs it to be. You're not going to spontaneously dry up. Severe supply decrease usually only happens if a) you get pregnant, b) you consistently take a combined estrogen-progestin contraceptive (which would only decrease your supply, not make it vanish) or c) you mismanage breastfeeding (schedule feedings, don't nurse enugh, pump instead of nursing, etc.)
The problem here is likely a combination of b and c. The morning after pills are like a one-time high dose of combined estrogen-progestin pills, and that's likely to cause your supply to decrease. And instead of nursing, you had two 8 hour periods of simply pumping, which tends to be much less effective than nursing when it comes to maintaining milk supply. But the decrease should be temporary, since a) you're done with the pills and b) you're back to nursing. At this point, nursing the baby should bring your supply right back.
On to supplementing: just watch your baby. If he continues to have adequate wet diaper output and generally appears satisfied, don't worry about supplementing even if your breasts feel less full or if baby is nursing all. the. time. Nothing is better for supply than constant nursing, so if baby spends a couple of days attached to you, I think you're going to get right back on track.
Now, if baby is not wetting the minimum number of wet diapers in a 24-hour period, then you may need to consider supplementing while you work to bring your supply back up. But I don't think you're going to need to do that.
