My first question would be...are your cycles "regular" or "irregular". If you are "regular" like clockwork, than it could be possible. However, if you have "irregular" cycles, it makes it harder to determine.
In my case, I had irregular cycles and it took me 7 years and lots of fertility advice before I finally conceived my twins. I have PCOS and my cycles were every 6 months if that. We finally went to high powered fertility drugs and got pregnant the first time.
However, after the twins were born, my cycles have be slowly but surely become regular, which to me is very strange. I'm 39 and conceived my twins at 34, almost 35.
I agree with what the ladies are saying that you could be "testing" too soon. Espically if your cycles are regular. And also some times you may never get a + result on the over the counter pregnancy test...you may have to have blood drawn to find out. If you have insurance and your dr would give you the paperwork for it, that might be a better idea.
I would suggest contacting your doctor if you haven't gotten your cycle in your regular time, to make sure there isn't something else going on.
Everyone say to "RELAX and it will happen"...makes it hard to relax when you are having issues trying to conceive. Trust your body and your gut feelings on it.
I will put you in my prayers for guidance and wisdom on this issue for you. Please keep us updated, so we know if this is the month or not. :)
Take care,
God Bless,
