AF is 25 days late! ‼️ HELP!!!! ‼️

Meghan
So around the time my period was suppose to start I started cramping like I usually do, nothing unusual. Well then my period never came and the cramps continued. They weren't horrible just uncomfortable. Mind you my period is never regular usually between 5 days of when I suppose to start. But now here I am going on day 25 with still no period. I have taken 4-5 pregnancy test and they all came out negitive (except the first one which showed a faint line but I was told that it was an evap line). The first couple weeks after AF was suppose to come I started spotting which isn't normal for me. I started getting worried so I called my doctor. That's when I found out that he retired and I wasn't informed. So now I'm have to find a new doctor which isn't going well. Does anyone have any ideas as to why I am so late or what can cause this? Anything is appreciated!
