Just as an update. As the week progressed it seemed a little heavier and I thought that maybe it was my period but just a touch lighter because I had already lost some the week before. Then on Monday my flow became more normal and yesterday and today I have a normal heavy period with the normal cramps and all. I am just hoping that my cycle will be normal now and I won't spot afterward. This last week has been less stressful as I am comfortable doing the field work and my stress definitely decreased so I think it was just the stress of everything including this issue. If I had not come on by the end of the week I was planning to see a doctor, but hopefully I won't need meds now to get back to normal.

Thank you all for the replies.
