Constipation

Shetomar • I`m 38 married 17yrs. Currently PREGNANT. M/C #1 Aug 2013 at 7 wks. M/C #2 Jan 2014 at 18wks, M/C #3 July 2015 at 16wks Chemical pregnancy July 2016
I'm only 4wks +2dys and I'm having a terrible time trying to go number2. Is constipation this early normal or is it something else?
