Advice please!

I'm on cycle day 44 almost, with my period being 15 days late. My cycles aren't longer than 32 days ever. But I've had 4 negative tests, last one taken was two days ago. Using the dollar store brand. But I haven't used morning urine. (Does it really make a difference? ) anyways for the last week almost I had very heavy creamy CM and the last two days it's light creamy. Mild back aches and frequent urination. I don't feel as if my period is coming but I need to know if this is normal, or if I should call my doctor? Not sure when the cut off date is for tests.

If you read this, thank you. If you have ANY thought, please comment!

I'm 23, 2nd baby.

Also had my Mirena removed 7 months ago, but have had regular periods. And this is my first month using glow and logging ttc.
