Scared

Amy • Mum to 4 year old Phoebe. Me and my partner Ryan are currently trying for baby number 2 X
My period is a week late but I'm so scared to test incase it's another no. My periods have been irregular for 2 years but since January have regulated to 28 days and now this month it's now day 36 and nothing. Should I have any pregnancy symptoms yet. I've had no period pains either. I don't know what to do. Help x
