DPO Symptoms & Baby Dance

So far I’m 3 DPO and I’ve experienced several different symptoms already but I’m not sure if it’s due to conception and was hoping you guys could help! I’ve had massive heart burn for the last two days and haven’t even been able to sleep! I’ve been nauseous and even threw up yesterday. I’ve also had leg pains and daily annoying headaches. On top of that my bloating is out of control that I can look pregnant at times, I’ve had cravings that for things I’ve never desired to eat before and my breasts are starting to get tender. I’ve never felt this way before after ovulation, maybe bloating every now and then but nothing like this. Am I over thinking it? Also I’ve attached how much my husband and I baby danced! Was this enough? We’re hoping for a positive soon! 😭🤍
