Hi there
if your cycle is usually a 28-33 day cycle, normal ovulation should occur between day 12 and day 17 of your period. Providing, you have a normal period (same time every month).
This early in the game may be too early to tell. Count from your last period date and count forward those 12-17 days- if the feb 8th date falls in that time frame- there is a possibility.
However, you should not even have those symptoms yet. There are times you can worry yourself about being pregnant and trigger your body into having the syptoms. Hunger can be triggered by the onset of your period too. The first thing to look for is the missing period or breast tenderness.
Give it a couple of more weeks and then take a hpt or go to your doctor for a blood test. And don't worry.
Good luck!
