Hi ladies!

So, my period is due tomorrow. I've taken a few tests and all are very negative. But, my boobs are pretty sore, and I feel no period cramps. This is very weird for me. Typically I have pretty bad cramping before/ during my period and I've really had nothing. I've had mild period like cramping between 4DPO and about 9-10 DPO but the last few days pretty much nothing! Now I'm just pretty gassy and bloaty and tired, small headaches here and there. Has anyone experienced this? Could my period just be changing? I thought it got worse as we got older? Thanks!
