38 and confused

Hi everyone. I had the essure procedure done like 10yrs ago and had no issues with it. Then I just recently had my period and it was weird it started out light then went brownish after a day so I freaked out and took a pregnancy test and it came back with a faint line but then my period went red but not red red. I had really bad fatigue with this period and my boobs started to hurt so I retook a test only for it to come out negative. Then I know this is weird but checking my boobs I checked to see if anything would come out and milk did so I took another test to only get another negative. WTH.
