How to know???/

Oky so I had been reading a lot about miscarriage and comments of other ladies that went through it, and most of them said that they became pregnant right after their miscarriage. Me and my husband TTC right after the bleeding of the miscarriage stop. It is 5 weeks after my miscarriage now and my question is, how do I know if I am already pregnant or what is going on. Because I did not start a menstruation yet and I've been feeling weird this last week. When do you ladies think I should do a pregnancy test? Some ladies said they found out at 2 weeks after the miscarriage. Should I test now or wait? sooooo confused!!!
