Irregular periods!

Ceinwen
Hey ladies I have been trying to conceive since July I came off the pill and by September I had a 'normal' period. The next one was 45 days later then 25 days later, after that I figured that I would be back to normal usually between 25-30 days however it's been 50 days since my last period. Has anyone else experienced this when coming off the pill? How long does it take to get back to normal? Obviously I have the thought in the back of my head I could be pregnant but I don't want to take the test incase I'm not as it's my first 'could be pregnant' I guess I just need someone to tell me to jump and do the test! 😊
