Hi I Had TOP On The 5th Of May When

hi
i had TOP on the 5th of May when i was 4 weeks far i passed few clots at night and after a day bleeding stopped morning sickness was gone no more cravings. i went to a doctor the scan i did was clear there was nothing on the uterus. 4 weeks later i was still passing out brown discharge and the pregnancy test was positive i went to the doctor we did the scan and it was clear. we repeated the TOP again on the 14 of July and i passed few clots again and i was bleeding for 10 days. first week of July i went to the clinic to do family planning the preg test was positive but this time t was too faint that you cnt even notice it there, they refused to do family planning and transfered me to the TOP clinic. I explained everything the doctor did vaginal ultrasound the uterus was empty and clean. The docter adviced me that we do blood tests just in case i have ectopic pregnancy she will see if the HcG levels are dropping or increasing that will determine if im preg or not I did blood tests for hCg levels it came back with 23h and did 2nd blood test after 3 days it was 16h. the doctor then referred me to family planning clinic and they gave me 3 months Depo shot on 13 of July. After it have been feeling very weird, cramps like period pains, lower back pains, lot of watery discharge. On tuesday morning when i woke up my pjamas had lot of blood i went to the toilet and passed a clot and was bleeding whole day. next day it was just spotting only and this waterly discharge but it this time it like it has small amount of blood in it. So according to scans and blood tests im not pregnant. Im worried are this side effects of abortion or Depo side effects, my hormones are abnormal? Please assists im very stressed.
