So I have very irregular periods and we have been trying for a few months now, as per the app I use I am 5 days late for my period I took a test and it come up positive within the time frame but looked at it again a few minutes later and it has disappeared completely? I have a stuffy nose, mild cramping and not really any sickness other then when travelling in the car which is very unusual for me! What do people think?! Has anyone had this before and turned out to be BFP?
