Pregnant?!

Im 28 days late on my period! Hubby and I have been trying !! I took a pregnancy test on day 26 it says negative but the weird thing is my nipples have been sore. -!

I’ve also been spotting off and on!!! This is driving me crazy!!

Been having vagina cramps and lower left and right pelvic cramps.

All my cramps I can feel me but they don’t hurt I definitely noticed them though...

So now I’m just freaking out a bit because I don’t want to keep buying pregnancy test and waste money...

Is this a normal thing or not! Am I pregnant ?

My last period was November 10 till the 15. I don’t have my period in December and now it’s January and I’m still waiting on it. Should I just relax and see if I miss another month of my period then take another pregnancy test !?

Anyone ever gone though this ? Please give me so advice
