Pregnant?

Li

What are my chances being pregnant? I know we didn’t have sex much since were so busy with our work schedules. But we did have sex on January 28th and ovulation was on the 31st. I know that testing right now is not a good idea since it’s too early to take but I just wanted to see what it would say. So took a rest And it came back as positive. Very faint. I’ve been having sore boobs and very sensitive nipples hurts to the touch. A little cramping. Heartburn. My body tells me Iam pregnant. But I don’t want to have my hopes up high and turns out I’m not. So my question is when is a good day to test? I don’t know my DPO since I didn’t take a OPK
