Late period?

Liliana

Hi guys so I’m 5 days late for my period. I took a test the day after my missed period, the day after that and today and they all showed negative still. I also breastfeed still but I’ve had my period consistent for 3 months now and this is the first time that it hasn’t come. My question to you ladies is, do you think I could be pregnant even if it’s saying no or do you think breastfeeding could have affected it? Thanks I’m advance!
