My husband and I have only been ttc for 2 months. I am 30 years old and my period has always been very regular (every 28 days). This past month I started on the day that I should, but it only last for a day and a half. It is normally very heavy and lasts 5-6 days. It stopped for a day and then I got a very light pinkish brown spotting for just a few minutes. I know there is always a possibility of being pregnant , but I m not really having any symptoms. I have had some slight nausea at times, but that is all. If I were pregnant, I would be about 3 weeks. What do you think?
