First pregnancy symptoms

My period is 6 days late and usually it can be off by a day or 2 but never this late , since I’ve had a miscarriage in May. I’ve been ttc since.. recently I have been EXTREMELY tired, not like my self. My back will hurt so bad and I find it really hard to get comfortable and go to sleep. I’ve also had cramps that feel a lil less intense than period cramps but no sign of it. Sometimes I get this weird pain in my boobs but they aren’t tender like when I was pregnant before. Just curious has anyone had these symptoms before they knew they were pregnant ?? If not comment your first symptoms!!!
