Advice please, depo injection messed up my body

So back story I got my depo and it finally expired or was due a new one 28th of march and my god the last three months have been hell on earth, I’ve practically been on my period for the whole three months and I’m now about a week over needing a new one which I won’t be getting because I’m re starting my ttc journey and I’m still cramping and on and off bleeding to then spotting that then goes to like next to nothing and then bleeding again, I’m fed up and my body is aching, I’m consistently nauseous and tired and I truly just want this bleeding to go away now, I can’t go to a gp as I’ve just moved and haven’t had time to sign up yet, any suggestions or tips or advice on how long this bleeding could still be going on because I’m mentally exhausted 😭😭
