Time of the month

So it is my time of the month, but I have worry and concern about this one and the last previous one a month ago. So the first time this had happened was last month, the color was abnormal, it usually started off brown before going to the normal red. Well this last one started out as spotting pink, I have had this happen before and went to a doctor so I was on meds. Any how this one was different, it stayed spotting pink for the first whole day before going to the normal red. Unfortunately I had one discharge and that was on the 4th day. Updating to this one happening now... I started while at work, it started as a maroon red which was odd for me. I couldn't think much of it because I had no time to do so due to fact being at work and needing to rush out of the bathroom to do my work. Anyways, I'm on day 3, I still havent had a discharge and I'm used to it also happening when I wake up but it has not been the usual and I am not sure what to think or do about it. Is this the new normal?? Or should I have lot of concern and see my doctor??
