Should I test?

Paula

So, I am due for my period today. Nothing yet. I’ve had zero spotting, and I normally spot for a couple days before it arrives. My boobs are sore, but that’s not uncommon for my PMS anyway. I have sever endometriosis and I’m not young…. So it’s highly unlikely that I’ve conceived naturally. But I’m surprised at my lack of normal period signs…. Estimating I’m 13dpo.
