I would say first of all dont worry and stress over it, that will only make it worse. The single most important thing you can do is to drink lots of water and eat well. With both my kids I had contractions super early and even dilated early. Each time they talked to me about early labor and everything and each time I had to get induced because my body didnt go into labor on its own and my first was late and my second I was leaking amniotic fluid both dilated to 5 cm and by then with both I had no more contractions. Every body is different, and its actually completely normal to have contractions that early, most woman have them as early as their first trimester drs are finding, but arent feeling them. As long as they arent dilating your cervix that early, they are completely fine. My contractions started at 25 weeks with my second, and by 30 weeks I was having them all day long every day and most days they were 3-5 minutes apart, but I didnt start dilating very much until the very end of my pregnancy. Normally they wont check you for dilating until you are further along because of the risk of setting you into labor, but as long as you havent lost your plug, or still have contractions every few minutes there is no reason to be concerned or even to get on meds. Most people with twins end of going on bedrest as well, your body has extra weight and pressure on your cervix that singleton moms dont have. I pray that everything goes well for you, and that you have healthy and happy babies!!
