Help- I need help figuring out my new birth control pill start date.

So I went back on the mini-pill at 6 weeks postpartum then I got my period the following week and my period has been all over the place ever since then and not following the B.C. 4 week timeline. Now that I’m not pumping anymore the nurse switched me to a regular B.C. pill. She said to start it after my next period and I don’t know what to do —— Start after my last sugar pill or wait for a period then start the new pill?

My period has always been very regular and predictable so I don’t know what to do or how to predict an irregular period.

Here’s screen shots of my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> with my birth control schedule in yellow with the blue line showing the 4th week/sugar pills when I should be getting periods. Ignore those turquoise ovulation predictions- hopefully the B.C. is stopping that!!!

SO......

......Should I start my new B.C. pill prescription on June 11 the day after my last sugar pill of the mini pills?

......do we use condoms for a while and I wait for my period to come and then Start the new pill?

....when do you think I’ll get my next period?

......I haven’t gotten my period on this sugar pill week yet (still a few days left, but I used to get period within 1-2 days of first sugar pill). We haven’t been using double up protection cause I’m on the pill & haven’t missed any pills. But now I’m questioning things. Is it possible I’m pregnant again?

(Also if we do get unexpectedly pregnant we won’t be too freaked, we do want more but had planned on waiting a little longer but not years to try... hence the pill)

Thanks for any help you can offer!!!

And sorry for the long post!
