Breastfeeding mom might be pregnant

Alana

Hello guys! Desperate for other opinions and thoughts. I had sex on ovulation day which was May 6th. My period was supposed to be due May 22nd, but I never got it. I did a at home urine test on the 26th and it was negative. Did I test too early? I am breastfeeding as well so I’m not sure if that might play a part? So far symptoms are leg aches, lower back pain, and huge appetite, when I think of certain. Foods I get sick. I just feel like my body’s feeling different. When should I test again?
