Could I be pregnant ?

Maria

Okay so I wasn’t able to grab a picture Bc I unfortunately didn’t have my phone on me and I’m at work, I went to the bathroom I wiped and there was a medium sized glob of stringy egg white CM. AF is supposed to start tomorrow I’ve been ttc for a while now since my miscarriage a year ago. Could this possibly mean I am pregnant? I took a test a few days ago and it said negative but I know that can be too early. I found a picture to show what it looked like! My breast have felt heavy and REALLY tender like hurts to take my bra off or sit up and let them hang tender. And I’ve had occasional cramping which I usually don’t have before my period. Let me know what you think ladies.
