Help please

I don’t know what to think right now. I had a nasty chemical in September that resulted in an infection. I was so excited about that pregnancy and was devastated with the outcome. My period should have come yesterday or today and I’ve been cramping for 3 days now with nothing. I’ve struggled with my attitude- poor hubby- and keep having to check myself because there’s no reason for the mood swings. My face is always clear but I just had a breakout on my forehead. I normally have a lot of discharge by this time and I’m not. I am having a severe eczema outbreak on my hands/arms/breast and my allergist today asked me if I could be pregnant- perhaps it’s hormonal. Do you guys think I should test or just wait a few more days because the recent chemical could have me all messed up? I hate this feeling of not knowing. 😔
