I usually have a normal period ,but this time it was different. I started 12/25/10 and it usually runs it's course in five days. Usually it is very heavy and I cramp for a day and a half and it is heavy all through it. But, the one I had Christmas was very heavy the first day and I cramped. Then I spotted the rest of the way through. I don't understand what is going on can someone please help me?

Yes, me and my husband are trying to have a baby and have been trying for almost a year. Although, we have not had any luck we are hopeful can someone please let me know if there may be a chance or if there maybe something else wrong?
Please, all input is welcome. Thanks
