Anybody else have irregular periods? I have 2 apps that help with cycles glow is saying I am ovulating today till the 6 due on the 14th my other app is set at 50 day cycle at all times it's saying I was fertile 22nd to 28th due on the 10th! So I have followed the first app so far and the passed 2 days I have had cramps and sore boobs! I feel like it's 2 early for me to come on as I have never had cycles less than 50 days so am I Even ovulating but I do have a 4 year old so I must be at some point! So annoying cos I have no idea where I am with anything would you say the cramps were implantation or do u think it's af making an appearance early 🤔🤔🤔
