3rd period in 3 weeks POP

Hi, I’m wondering if anyone has experience or insight that can be helpful. I’ve been on the minipill for about 10 months now since my baby was born. I’m still breastfeeding 5 times a day and I really was hoping to continue as long as she wanted to. But, 3 weeks ago I got my first period since baby was born which sucks but whatever, and then 5 days after it stopped I got another period. Doc said my body could just be recalibrating. Now it’s 1 week since that period and I’m starting to spot/bleed again. I know spotting is a pretty common side effect. I’ve been diligent about taking it at the same (exact) time especially since my period came back but it doesn’t seem to help… is there anything I can do or is my only option to switch to the combined pill and hope it doesn’t effect my milk supply too much…
