TTC Help

had my period July 27th Which was 2 days early, then it ended July 29th the day I was suppose to start. Then we BD that night n it started again ended the 30th. I haven't gotten a ovulation kit yet but could feel when I was ovulating which honestly is weird. So I started feeling cramping on my right side August 6-12th. I also have been having a high sex drive which I'm not use to n I'm 26. If we don't get pregnant this time were going to the doctors. I was on BC Pill for 5yrs been off for almost 2yrs, did a test it was negative. Do i have a chance or should i go to the doctors .
