HI, Basically Im 22 Years Old, Had My First Last

HI, basically Im 22 years old, had my first last year may 18th 2015, no problems with birth, forceps and tear, 1 and half weeks post parturm bleeding. Then I had the nexplanon implant for 6 months but had on off bleeding every 2 weeks. I then came off that and a doctor insisteD even though I planned to have a baby again soon to have depo jab, I still bled every 2 weeks for a week. Quite heavy. Then after 3 months I was due another jab but I didn't go. 6 months later a returned period, then I've come off a week, and now back on again and it's been 5 days again. Im not sure what's going on but I'm planning to have a baby with my husband, but I know i can't ovulate if I'm bleeding all the time. I've asked doctor to refer me to a gynaeocologist but I've been waiting 13 weeks now and I'm getting impatient. Im stresseD and confussed on what's going on. I need advice. Thankyou
