Period?

I took my iud (mirena) out 2 weeks ago. I bleed for 5 days and then stopped for a few days and yesterday I started bleeding again. I’m very emotional, my boobs are sore and look like they are getting bigger. I’ve had irregular periods my whole life. I just wanna know what’s going on I’m so confused to why I’m bleeding again..🤷🏼‍♀️😭HELP PLEASE!
