Question

I started birthday control on July 11 for my first ivy cycle. I took my last pill on July 29th because I was suppose to start my stims on 8/2 Well none of my meds arrived on time for me to start them so I have to start a new cycle of birth control on my next cycle. I started spotting very mild on 8/1-8/4 and my cycle was due 8/9 . Is it normal for bcp to delay your CYCLE? When I told my specialist she said ok it’s normal. I’m still waiting on my cycle and becoming inpatient because I’m ready to get the process started again.
