Okay, I've breastfed my daughter since she was born, she's about three and a half months old now, i started the mini pill about 8-11 weeks after having her. I took the pill halfway during my period, it lasted about a week, and i haven't had a period since and i'm about 2 weeks late. i hadn't had a period until that week that i started the mini pill. i'm also working, so i do have some stress on me. does it sound like i'm pregnant, or is it normal for the pill plus breastfeeding to make my period irregular?
Whenever you start the pill, your periods can change. This includes missing one completely, or never even having periods.
But, do you have any reason to believe your pill may have failed? Have you been taking your pills every day at the same time?
