My period is 9 days late!! What should I do?!?!

I’m alittle worried that there is something wrong with me. I should have started my period 9 days ago. I’ve taken three pregnancy tests when it reached day 6. And all were negative. And normally I would be feeling cramps that indicate I’m due to start my period any day. But I’ve felt no pain at all. I had my contraceptive implant removed three months back because it gave me issues. I had that for seven yrs. When it was removed I began a period 3 days later, lasting 8 days. And the following month I was on time with my period too, again for 8 days. But this month I don’t know what happened to me. Maybe it’s also worth mentioning that three weeks ago my partners condom broke so I had to take a morning after pill. Could it be the morning after pill delaying my period? Could it be my body is a little inconsistent while still trying to get back into the natural rhythm of things after my implant? What do you think it could be?

Thank you for your help!!
