TTC. My period came Sunday morning, it was late, but only by a day. Heavy Sunday, by the end of Monday there was nothing on the tampon I was wearing. I had really painful indigestion in my upper abdomen the day before and day of which is now back. Today I had some light brown spotting. My period is typically spot on the day I have in my calendar when it should arrive according to my cycle. I also don't have constant indigestion like this - ever. And period typically last 5 days. I don't know what to think other than this is very strange for me.
