Normal Period or Rare Pregnancy Period?

This is the first time in over a year that my husband and I have been able to try for another baby, as we had been successful in 3 weeks time back in 2008 when we got married. But at the time he lived in the Philippines and I had to get back to my son in the States, and after arriving back, I miscarried, due to stress and depression, in September 2008 after nearly 2 months along.

On the 8th of Dec my monthly arrived like normal after 32 days in between the last one It lasted for 8 days and as normal it's usually always heavy from start to finish with no light days before, during or after.

My fertile days were from December 23rd to the 27th with the 26th being my ovulation day. The hubby and I BD at least once a night at bedtime and once in the mornings before coffee. We both have high libidos, and after a year and a half apart we act like newlyweds, and during those fertile days more then twice a day.

During the first week of January I have had sore tender breasts, very moody to the point of snapping on everyone for no reason, feet and ankle swelling, increase in appetite, frequent urination, headaches, an increase in indigestion and heartburn, and some diarrhea all of these things uncommon for my monthly symptoms. Usually when my period is going to start I only have frequent urination and lower back pains instead of cramps.

The 9th when I was supposed to start, I had very light spotting, that lasted for 4 days and then 1 day with slightly heavier spotting and minor cramping, then back to 3 days with very light spotting. While this is my normal length for a monthly period, it is not the normal flow and symptoms.

So what I am wondering is could I be pregnant and this is just the spotting and light period that is possible but unlikely when pregnant? Or was this my actual period?

Any help or insight would be greatly appreciated as this is confusing the heck out of me and I don't know what to do or think.
