missed period last month & spotting this month

Honey🌚 • 29. Pcos. Married. 👶🏻💙2/22/2020
I missed my period the entire month of January. During that month I had what seemed to be implantation bleeding. When I was 6 days late I took a test and there was a extremely faint line. I took another two days later and nothing. Even at doctors office it was a negative. They did a blood test but I won't get the results for that till march 2nd when I go in. Fast forward it's February. Nothing this month either. I'll just spot on and off especially when I wipe. During January I felt dizzy, had cramps, back pains, nausea, heartburn and all the symptoms that disappeared in February. I am so confused. Has this happened to anybody before? I thought my period had started on February 17 but once again it was just light bleeding when I would wipe and it was brown in color. Usually my period blood is bright red. It only lasted about 5 days. I am not stressing about anything. Nothing has changed in my routine. I eat the same exercise the same and all. I am getting worried now 😭 when I exercise now I can't go past 30 mins without feeling pain on my right side of lower abdomen. I used to exercise for 1 hour and 30 mins straight without ever getting tired. Just this Sunday I randomly caught a cold and had a fever for 3 days straight😭 i am scared
