No period yet bfn tests

My period was supposed to start lastnight.

Hasn't started yet, boobs are so sore, I'm so emotional and so tired. I've had these symptoms before when I was pregnant with my other two children (5&7years old) I had my mirena removed after 5 years haventhad a period in god knows how long, and I had one last month.

It was so short and light (which is weird for me)

But idk has anyone else's periods after Lorena gone back to normal?

How hard was it to conceive?
