I'm 1 month and 3 weeks late and a day late

I have a lot of symptoms like- nausious,dizzy/lightheaded,headaches,fiatgue,sore breast jitters in my lower stomach,sides and lower back hurt a lot and even really sharp pains between my side and middle half of my stomach.

I took a h.p.t Friday morning, but it was negative.
But still no period.
So when is a good time to take another one because I don't know exactly how long it has to be before I take another one, but this does mean I still have posibility of being pregnant correct?

And me and my fiancé do not use protection, were trying to concive.

Also I've got a pudge am pants fit a little tight which is very unusual for me

I suggest calling your doctor ASAP to order a blood test.

Its possible that you are pregnant but a HPT is giving you a false negative.

Its also possible that you ovulated later than you thought, causing your period to be delayed - just one more reason to speak with your doctor.

A late period can be due to many factors - since you're over a month late, its time to get checked out.
