Confused about period!

Vivian
Wondering if anyone has come off their pill & got a period a couple days later.. Normal symptoms/ normal period. 
Then it comes time to have your next period (28 day cycle) and you don't get it. I've taken 2 pregnancy tests within the last week & their negative. I'm currently on CD 34. 
If this happened to you; when did your period get "back to normal" if you have a normal cycle?  
I must add, I would skip my period monthly due to pain before I went off it. I was doing that for a couple years. I've been on it for 10 years total. I want to believe I'm pregnant and it's just too early. But part of me wants to be realistic since my husband and I have only been trying for over a month. 
Tia! 😘
