Ladies I need your suggestions

So let me start by saying my Af arrived one day late it was red for one day than turn to brown light spotting didn't need no pad I could even have sex it was so light. It lasted three days that's all so technically I had one day period never happened to me before. Now I've been feeling nauces and tierd not sure what's going on. Idk if I should test or wait till next month see if I get my next period .. Did any of you experience this ? And ended up pregnancy
