7days before AF suppose to arrive

Gisell

I am just curious to know if anyone who is pregnant has experienced lower back ache 7days before expected period ended up with a BFP.. in September I miscarried at 9 weeks but used pull out method so didn’t expect anything of it until back aches and tested 3days before AF and I was pregnant... I am tempted to test later but idk if 6days sooner test will show 7days before expect period...
