Symptoms before BFP?

I’m not currently pregnant but am TTC and figured I would have better luck asking ladies who have already conceived. I believe I ovulated 3-4 days earlier than Glow predicted, just based on my body. ( I do not use OPKs and have no interest in doing so) anyways I think I’m about 8-9dpo. I know this is still very early. Since about 6 dpo I started getting some slight cramps and twinges, and today I’ve had really sore hips and legs, as well as some soreness in my lower back. The last 2 days I’ve had a headache and this morning some slight nausea after I ate. I still have more than a week before AF and even if AF were to come early, these are not symptoms I get with AF. Wondering if anyone had any of these symptoms before getting a BFP?
