Hoping im pregnant, but worried im not.

I am currently on day 32. For three months in a row i had a 25 day cycle. Last month it changed up a little and it was a 29 day cycle. So im not sure if im 7 days late, or only 3-4 days late.

Here are some symptoms i am experiencing. I am smelling things, its kind of hard to explain that one. I smell random things, for an example, i smelled spoiled milk yesterday, but i couldnt find the source, and it almost made me throw up. Ive been nauseas lately. My husband had a salad container in our bedroom from lastnight. I took the lid off of it so i could put orange peelings in it, and i smelled the ceaser dressing and it almost made me throw up. Ive been craving certain foods. Other foods make me turn away. I have lower back pain. My nose is a little runny-cold like symptoms. (its been really warm where i live at lately.) And of course, im late.

Also, since im late, and im not sure how many days im late. When would be a good day to test? Is tomorrow morning(morning urine) to early?
