Hi, I Know This Has Been Asked A Lot But

Hi, I know this has been asked a lot but I want to share my experience in detail. I had intercourse about a month ago and two weeks ago and have been taking pills for three months now and to be frank , it has not been consistent. See below:

I was supposed to take my last 3 pills for this month on 19 to 21 May but instead, I took 2 pills on 21 May and 1 pill on 22 May. This happened to me about two weeks ago as well. And I am not sure if my period is delayed but I know it should be coming any day this week.

I took PT on the evenings of 23 and 24 May but tested negative. I am really worried as I just gave birth Sept of last year and not ready for a second one yet.
I made an appointment with the doctor by end of this month but quite anxious and thought of sharing my situation here. Thanking in advance for all your help!
