Boob questions

So I'm now 3 days late for af and Today I started having more pronounced boob twinges and aches and idk if this is weird but my nipples are hard like 90% of the time which is definitely not normal for me. Ive also had lower back aches and hip aches. I want to be pregnant so badly!!! Hoping these are good signs. . I've had other symptoms like indigestion and lots of burping, tired, and bloating.
