Curing constipation.

Rebecca
Sorry if this is TMI, but is anyone else really constipated? Last week I had to take laxatives (senekot which my doctor said is fine) as well as prunes after 5 days of not being able to . Today I am back at day 3 and still nothing. I have tried increasing my liquids and adding in more fiber but nothing. I am about my prenatals to one that has iron. Any tips on what I can do?
