Menstrual in general has been weird?

This whole ordeal started in the end of May on my regular schedule. My period was heavier than usual on the second day, I am pretty sure I soaked through my pad in an hour or two. Any ways I didn't really think about it after until around the 9th of June when I started to experience spotting that lasted for a week and a half. I did go to my doctor and she checked everything, I even did a urine test. She didn't find anything abnormal and told me that she was not going to check for cancer because I am a virgin and not sexually active. My cycle in June did come late, it came on the 4th of July, but I just blamed it on the earlier incident. Everything was normal. Then on July 27th I began to experience what I call a period again. This whole week my period was lighter than usual and it is scaring me. I usually get cramps or experience mood swings but this time there is nothing; I feel like I am not even on my period. The bleeding early on was not as light as spotting so it is not the same thing that happened in June. Now though, being it the 5th and last day of my cycle (usually), I am experiencing bleeding that it there when I wipe but does not go on my pad so its almost like spotting with bloody discharge. I am really confused and I don't know what to do or if this is even normal? I am not experiencing any pain anywhere.
