Missed 4 birth control pills

.

I had a baby four months ago And I’ve been on the pill

For about 3 months. My childhood dog recently died and with motherhood and loosing my beloved dog I forgot to take 4 pills these past 4 days. How can I get back on it do I take all 4 pills ): it’s the one they give to breastfeeding mothers the one you take at they same time daily. Thank you for feedback
