Hi Everyone!

Just wanted to ask you all a question.....

I am 15DPO (well got a + OPK on the 7th) and AF hasn't arrived yet.
I usually have a 30 day cycle. As I'm only 2 days late I did a HPT this morning & got a Is there anyway it could be too early and that my hormones are not detecting that I'm pg yet? I know AF could come any day but has this happened to anyone? Could there be a possibility? I have been getting very tired in the afternoons and have had a huge skin breakout!
