I just had my 2nd son 2 weeks ago. Thru the whole 1st and 2nd trimester I had bleeding off and on. Sometimes heavy, sometimes light. My son is now happy, healthy, and here! It is a terrible worry though, all I did was live in worry and fear when it happened. My dr. put me on prometrium for the 1st trimester too because my hormone levels were down a little. But like I said, my son is now here with us and healthy as could be! Even though you're going to worry, try not to so much, knowing that some bleeding in pregnancy is just normal for some of us. I wish you all the best!
