HELP PLEASE!!

Hello everyone!! I have two babies one 3 one 1&1/2. I stopped taking Micronor on the 23 of November mid pack. However my last period ended just near the second week of the 4 row pack(my cycles were normally between 28-34 days on bc, other wise every 28 like clockwork). I was supposed to get my period December 8th . I had such bad cramping that i for sure thought it was going to hit me (i had ovary pain) but nothing , then the 3rd&4th day i had terrible cramping I’ve been rushing back and forth thinking I’m getting my cycle but nothing !

Now for the past 2-4 days my boobs feel heavy and I’ve still had pms cramping . I have also had discharge ,nausea and heartburn. I tested the 8th of December at night it was negative . I’m now 9 days late no bleeding has happened , not even a withdrawal bleed. Since I’ve been off birth control my husband and i have had unprotected sex but he has pulled out , while on the birth control he did not. I’ve also had high irritability and trouble getting comfortable and 2 days ago i had terrible back pain when i woke up.

Is this normal from coming off of the mini pill?
