Charlene

So I have recently been trying to conceive w my bf for 2 years now , but I just recently missed my period last month . My last period was sep 19th -21 I've taking 2 pregnancy test but they were negative, but I also think it was to soon I estimated the time and If i am pregnant I would be around 6 weeks Should I take another test or wait for this months period ??? I've been feeling cramps bloating uterus pain abdominal pains. What should I do .
