Help me please 🤭🤔

I'm interested to hear your personal experiences from you ladies that had a "period" and were actually in fact pregnant. I've just had a feeling I might be since about 8dpo. I've had nausea and pulling sensations. Anyway though, AF was 3 days late this month. Took a test that had a faint line, but I started spotting a few hours later so just thought it to be period. That lasted 3 days.. pink, brown, some red. No clots. Almost nothing on the second day. I always get sore boobs, extreme cramps, and tummy troubles with my period. I didn't have any of that. I actually felt great and happy those days. Now its 4 days past that bleeding and I feel so drained like no energy whatsoever and so nauseous. Tired but can't sleep. I work with the eldery and one of my little ladies keeps telling me I'm pregnant and rubbing my belly feeling for "kicks" 😳 Should I retest or am I crazy? I don't know anymore. My SIL bled for 3 cycles with my nephew..
