Periods changed now I’m ttc

Ra

Hello

Me husband and I have been ttc for 3 months now and I’ve noticed my periods becoming more irregular! 🧐 I have always been a 28-30 day cycle girl with a heavy flow! I came on yesterday and I’ve had 2 days of brow/pink spotting before starting my period this evening! Weird for me!

Has any one else experienced a change in their cycle once they’ve started trying to conceive? Wondering whether folic acid or sperm has anything to do with it as we always pulled out before! 🤔
