I’m not sure where to post this. I just need advice.

I’m so very scared. I have a 5 month old and I think I’m pregnant. I’m late and my test are negative but I don’t feel my period coming. How do I distract my self from constantly testing??! It’s all I can think about. I recently got diagnosed with bipolar type two disorder, and all of my doctors keep saying they won’t give me an iud until we figure out my mental health. My life is hard right now as it is. I’m just venting but I’m not sure what do. I just want to keep testing because I have that feeling that I’m pregnant.
