Could I be pregnant??!

I’m on cycle day 39 and no sign of AF yet. I’ve had for the past two days sore breasts which sort of feel and look swollen.

For a few days now I’ve had mild headaches, lower back pain, nausea but not to point of vomiting and some mild cramps more like twinges around my lower belly. I thought it was AF making a presence but not at all and I don’t feel like I’m about to get my period soon.

Also been experiencing an excess amount of discharge too but always clear, no spotting at all but pregnancy test came back negative 😞 should I wait another week or contact my dr??
