How soon does the average woman feel symptoms?

I’m 7 days away from my period. I’ve had off and on cramping since day 2 post ovulation which is now accompanied by bloating and off and on nausea and occasional nipple sensitivity. We’re not trying but I’d be THRILLED to be pregnant... but I guess I am just paying attention to every little thing.

My first pregnancy resulted in early term miscarriage. I had the exact same symptoms as with my 2nd pregnancy with my son. Exhaustion being my number one symptom. I might be tired but I drink a lot of coffee trying to get my en-suite going while still running my business lately so I’m not sure how tired I am. I’m feeling lots of stuff but this is different. It’s also been 3 years since I was pregnant so maybe I just don’t remember. Idk. Just looking for input. I usually am like clockwork and never feel anything until day one, so it’s just weird that I’ve been feeling strange for about 5 days now and it’s still a week from AF. Send help. And cupcakes.
