I am so confused, and need to kinda rant

Soo.... I am 25 years old with 6 month old twins, and I have been married for a year now. My husband and I want to have 2 more kids (I would prefer twins again), but he wants to wait. I know that a year from now we have to move, and it is not feesable to try right now, so I currently have an iud in place for the preventative measure.

Now my problem is that I am currently experiencing severe pregnancy symptoms while not being pregnant, and it sucks. My dr said that it is due to ovarian cysts. What makes it worse is that I also have severe baby fever where I feel that I am ready for more children as well as want to be pregnant so bad despite the iud being left in place. I am keeping it in to be responsible, but a part of me wants it out and to be able to complete our family now. I just wish I knew what to do, and how to control these feelings, but as the days go on, the desire keeps getting stronger.

I have talked to my husband about it, but all I get is confusion and a road block from him. His is dead set on waiting, and yet he keeps apologizing to me. It seriously doesn't help me in the emotional department. And these cysts are making my hormones and emotions flare up out of control, making this even harder. I really wish that I was pregnant, because it would make me feel better about these symptoms I have.

Sorry if this doesn't make sense, this is me ranting. This is the only way as of right now I can think of expressing how I feel.
