I Had A Regular Period On June 8th For My

I had a regular period on June 8th for my 5 days. My next expected period was supposed to be July 6th but it came on July 2nd and only lasted 3 days with maybe 1 day heavy but not like my normal periods. On July 13th my breast got really sore, sorer than they are for period and on July 20th I started spotting, it was only on the liner and no bigger than a dime, on the 21st at 8pm it became a little heavier but not extremely heavy (only a panty liner needed) it was reddish brown (like end of period) on July 22nd nothing in the morning until 1 pm and it was the same reddish brown and didn't even fill half a liner, On July 23rd, July 24th and July 25th I just spotted that reddish brown again no bigger than a dime and only on the liner. I went to have a pap smear at the ob gyn for this irregular bleeding and she took blood test but not for pregnancy for Anemia. I'm still feeling off and tired all the time. My period is due in 2 days and I have no PMS at all. I should say during the bleeding I did have small cramps on my lower left side of my stomach and on Friday 27th I have had a pulling sensation that follows my hip bone by my stomach. I'm just so confused. My periods have always been 28 days and bleed for 5 2 days heavy. Myhusband and I have been trying for close to 6 years but took a break from it in February of this year due to us getting married and me not wanting to be pregnant at the wedding. Help!!! please..
