DAE have a fear of pregnancy ?

I am 18 years old. I have one kid and I am on the birth control opill. Every other week for two months I was having a period I am on month three and it has been 14 days since I have blood so the irregular periods are already stressing me out. I am constantly googling stuff and asking ChatGPT why I’m feeling certain ways if I feel a little bit sick a little bit tired a little cramp or anything. I start losing my mind. I think I’m mostly scared because I’m not in any predicament or a mind space to have another child and literally gets so bad that I don’t like to even say the P word out loud or even type it fully what I’m googling questions I realize this cannot be normal
