Advice/Opinions?

I gave birth to my son on June 30. On August 1st I started a birth control. (A little bit of a back story before I got pregnant with my first child in 2019 I was on birth control and it caused me to bleed for 2 months straight non stop.) so I get a week and a half into this birth control and I start bleeding every day until the end of the month, and I’m definitely not going through that again so I stopped taking the birth control, but I haven’t bled since and I have no signs of a period. I’ve taken pregnancy tests and they’re all negative. Should I wait a little longer for it to show or? I’ve already had 2 kids in less than a year and I do not need anymore right now🤣
