My current period started with a few days of spotting. I have now been on an even flow for 7 days, and on my period which include the days I spotted for a total of 10 days. I did take a couple of aspirin pills during. I also had sex for the first time in about a year a few days before. I experienced a very low libido level during depressive states. Could there be a change in hormones, or was it the aspirin or something else that may be causing this. I also do not see that the blood is changing brown to show my period will be over soon, so I am worried about how long this will continue.
