Weird symptoms

Jordan

I’m on CD 22. I think either 7-8 DPO. I had 2 days with positive OPK strips. Trying to fight the urge to test but started feeling crampy yesterday. Today I feel like I can feel my pulse in my lower back and cramps in my lower abdomen. Anyone ever had that crazy pulsating feeling in their lower back and gotten a BFP? Maybe overthinking but we’ve been TTC for almost 3 years and nothing so I’m always hypersensitive to anything unusual. Thanks ladies!
