Feeling weird..

Ok, so I had sex try day during my "green days" which were the highest percentage days of conceiving! I now have been feeling weird the past few days. I don't have pain/cramps in my stomach but a strange pressure feeling. Been experiencing a slight stitch at times too. I have been extra hungry lately too. I also have been having an unusual clear discharge during each toilet visit. I missed my period also!
Do you guys think I leave doing a test for another week or so? I'm just so nervous as I have had a miscarriage before only 4 weeks into pregnancy!
