I have had 3 miscarriages in the past 2 of then we're st 7 weeks and the other one was at 14. I found out that I am pregnant again but I'm having period like cramps in my abdominal area off and on but I have sore books and feel sick every now and then I'm just wondering if that's normal or am I having another miscarriage

There is no "normal" pregnancy, some women have no signs except missed period, up till 3rd, 4th or even 5th month.

Also, why did you miscarriage ? Is there a medical issue causing it, Has that issue been addressed.

Because of prior miscarriage, you need to be under doctor care at once, to confirm best course of action.

I would have this checked out, especially due to your previous history with miscarriage. Pregnancy symptoms does not mean miscarriage isn't happening, or has happened. This is something only a doctor can determine.
