Opinions Please

I’m beyond frustrated this month! I got another negative test this morning with a beyond frustrating indent line on FRER. I’m thinking of switching to another brand at this point because every time they pop up I get this glimmer of hope. Anyways back to the point, I’m having lower back pain (just started this morning), really sore boobs, cramps, and my newest symptom is a lot a creamy cm when I wipe? I never have cm before my period and it’s due tomorrow. Can anyone give me some insight or is my body just completely freaking out on me? I know there are so many of you beautiful ladies that have been trying way longer than I have but it’s still so frustrating!!
