Pregnant and breastfeeding

Taylor • Married❤️24❤️3 boys❤️#4 in 2022

I haven’t had my period since February but I took a pregnancy test March and April. Negative. Is it possible for me to get pregnant even though I haven’t had my period since February. I breastfeed and I guess my periods are irregular. I don’t think I am. But I’m a little nauseous and it’s scaring me lol. I have a 10 month old and a 2 year old already.
