Stretchy cm before period?

Jocelyn
This is not normal for me, I haven't had this cm before I think ever that I've checked even before ovulation. Is this a sign of pregnancy? I took a test today and it was negative but a cheap test and I believe I ovulated later because I was stressed at the time with some family issues. My period is due the 30th and I was supposed to ovulate the 15th. Has anyone experienced this and had a BFP
