Bad cramps

Ashley
Having pretty bad period like cramps when they come. Which they come and go but when they come there pretty painful. I'm 4 weeks and 1 day. I'm a little constipated, tmi I know I'm sorry. Butt is that normal? Please someone help me I'm stressing myself out about it. I also had my blood test come back today the amount of HCG was 268 I go back tomorrow for another blood test to make sure it's doubled but won't know till Monday. The first blood test was taken at 3 weeks 6 days.
