Most sources have now agreed that getting pregnant quickly after a loss does not usually cause or contribute to another loss. We can't know what caused the losses, it is totally possible that it was two different things all together.
Many people have two losses (or more) and then go on to have a healthy pregnancy. I would still have testing done if it's possible (some docs won't test till 3 losses) and I'd have them check your thyroid if nothing else to be sure it's functioning properly.
