Trying to conceive

KB

Can someone please tell me what’s going on before I loose my mind ☹️ ? Cycles are normally bang on but they’ve been everywhere the last two! Normally only have a 25-26 day cycle and last month I had a 31 day cycle! Currently on cycle day 33 with a BFN yesterday! ☹️ I started spotting on and off on the 24th but it stopped on the 26th instead of getting my full period ?
