Breastfeeding and two days late on period

Hello,

So my period returned last month October 5 (5 months postpartum) which was my regular cycle before I got pregnant. (30 day cycle)

Anyway, today is November 7 and I’m two days late ... I tested negative... is there any chance I’m pregnant ? Or do you miss periods while breast feeding? I pump about 95% of the time since I’m at work and put him on my breast once a day and it’s not for long... are my chances of being pregnant good and it’s too early to test or this happens?

🤞🏼hoping I’m pregnant🤞🏼
