Early pregnancy symptoms

Ashley • Mommy to a sweet little man!
What are some of the earliest pregnancy symptoms you guys have had? With my first pregnancy I didn't notice anything until I missed my period and took a test. I've been noticing that it hurts to wear a bra, I've been nauseated, been feeling "off", whacky mood swings, and kind of a deep achy cramps feeling in my lower abdomen. My period isn't due until about another week and a half, so could it just be a weird hormonal thing? I've been subconsciously putting my hand over my belly and I'm genuinely thinking that j may know I'm pregnant already. Please tell me your experiences and opinions, I'd love to know if I'm going crazy. 😅 thank you!
