Pregnant and breastfeeding

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

I have two boys. A one year old and a 7 month old. I’m breastfeeding my 7 month old. My husband and I have sex once in a blue moon. And the first few months I didn’t have a period. Then 3 months straight I had a period last 2 days each month. February I didn’t have a period now it’s the middle of the month in March and still no period. Is that normal? Any breastfeeding mom had this before or could I be pregnant. I’m a little scared because I have two kids under two and three will be too much lol. Please comment
