SEVERE constipation! Help

Amyleigh

So I've suffered with constipation for some time. Due to taking medication due to my health/pain. I got pregnant last November and found out 19/12/2017. I stopped most of my medication. Since being pregnant I've suffered lots from constipation. Sometimes I don't go for 4-5 days and that's only a little bit between. Feel bunged up and have tummy aches. Also been feeling sicky. Was sick tonight but don't know if it's a bug or if it's the constipation or pregnancy. I'm 19+2 weeks

Thanks x
