I am 8 weeks late today (on my birthday lol). I have suspected PCOS but it is managed meaning I have regular cycles about 26-28 days without fail. My last period was jul 26th. I missed august and now I am 4 days late for septembers. I have taken HPTs and they all say negative. I had a blood test done the last week of august that was inconclusive. I have had some pregnancy like symptoms mainly mild cramping, fatigue, and excessive saliva. Can I be pregnant and just not registering on HPTs? or is something else wrong. I am not stressed and there haven't been any significant changes to my lifestyle to warrant a flow change.
