Nipples & Aches

SASHA • Mom of 2 boys! 💙👶🏽 KAYDEN & KARTER 👶🏽💙 9/21 & 1/19
I ovulated on the 21th of June and I've been experiencing back aches and my nipples are very sensitive and hurt. Is this normal? I don't if it's all in my head or my body is going through some changes and yes I know I'm not pregant to soon to know or even check. Please help... any advice
