I'm 10dpo and I'm having lots of symptoms

1) lower backache since 5dpo

2) lower pelvic pulling sensation

3) sore nipples that happened 2dpo that later for the days, now I have dark blue veins on my areolas

4)bleeding gums just started today.

I hate getting my hopes up but its hard not to. Having the constant dull backache is something new to me. It never goes away its always there
