Can switching pill brands help with breakthrough bleeding?

I

Hi ladies! I’m planning on going back to doctors next week but wanted to hear from anyone else who experienced this as well.

I was on Levlen a few years back and had great results, no side effects and no spotting at all. Earlier this year I tried again and had breakthrough bleeding for almost a month and it was so frustrating so I stopped. It wasn’t heavy but enough to leave a tampon in for the day.

I’m back on Levlen again for the third time to give it another go, I started on the first day of my period. I’m pretty regular with my periods and right now it definitely should have stopped so I know I am bleeding from the pill.

Has anyone experienced the same thing and changed to another brand of the pill and it stopped the breakthrough bleeding? A couple of my friends switched to Yasmin and no issues.
