should i test ?

On 13 dpo I had what I thought was my period but I thought it very strange because it was lighter than usual and there were no clots. Before I started bleeding I had pretty bad cramps on my left that kept me from sleeping. Never cramped like that before. That was also strange. The bleeding lasted for 2-3 days and was brown for 2 more days. Now I have very creamy and white cm. I dont usually have that either. I actually probably ovulated very late. Because I had temps missing on my chart. But I'm not 100% sure. Since then I have not had an appetite for anything. Unless I suddenly crave something. I get nauseas at night and my nipples look darker. I get headaches and acid reflux. I usually drink coffee every morning but recently it smells off putting to me andmyself to want to drink it. Should I test?
