so I gave birth to my first born

14 weeks ago.. and I started my birth control at 11 weeks post pregnancy (had to wait till my period showed up).. I've been taking it everyday since then. My birth control is not the hormonal one but the one  that won't stop my breast milk. My doctor warned me about not missing it because it wouldn't work if I did, and I never thought I would. Well yesterday I woke up at 3 in the morning to go to the airport to catch a flight because I was going to visit my mom so she can meet my son. Well I took two flights from 6am till 12pm. Then I went to my grandmothers from 1pm till 6pm, then I went to my moms and finally fell asleep around 830pm. I thought I took my pill because I remember my alarm going off but I just was looking at it and noticed I forgot :/ I guess I turned my alarm clock off..  I am visiting my mom for 2 and half weeks and my husband isn't here.. did I mess it up?... will it not work now?...
