Period question???

Allison • Angle baby boy💙 Sweet rainbow baby girl🌈 and expecting feb 2021🤰🏼

So I just had my daughter September 1st, I got my regular period back on November 16th and I started bleeding again November 29th, I didn’t think that was a period so I didn’t log it. Well it showed that I was 3 days late and so I decided to log it as a period and that of course changed my ovulation day. Well we had sex on ovulation day and the day after😟 I’m horrified. Yes I want more kids, but not 3 months after giving birth. So would you say the bleeding was a period and my period is still wack or do I have a chance of getting pregnant for the second year in a row in December...
