How to tell if it was a chemical?

Maggi

i had a VERY faint positive a few days ago. The response was kind of mixed on if people saw it or not, but I can definitely see it on the tweak. yesterday on CD 26 (when my last 3 cycles have been 31 days exactly) I started bleeding. Prior to this, my boobs grew, I was covered in veins, and was extremely hormonal. The latter is the only one that happens with pms for me. I have had the flu since Sunday (bleeding started Friday) I just wanted to get some feedback since I am feeling a little defeated. I had either a chemical, or miscarriage back in October and it broke my heart. I dont want to be sentimental about something that didnt happen, so I would love opinions. thanks in advance. 😢
