Took a tet this Sunday and it was a faint positive. took one the next day and both test were negative. waited two days and took one today and it was still negative. idk if I was just never pregnant and got a false positive or if I had a. chemical pregnancy. I've been having sorry breast, and tingly sensation around my nipple area. I do have mild cramping on one side that do go on and off. and my discharge has been creamy white discharge, but sometimes I see it's a watery clear discharge. anyone please some advice if this has happened to anyone?

this is the picture the test I took in the morning this Sunday.
