So I need a little bit of advice so me and my husband had sex on the 2nd and my period usually comes around the 14th ish. Well I cramped for 2 days and then bled for 4 days but very lite and the now for 2 days I'm still cramping but no blood. My boobs have a tingling feeling on my nipples sorry tmi, its only been 2 days since stopped bleeding and I've had a headache and some nausea. When should I test? Do you think I'm pregnant??
