Hi There, To Cut A Really Long Story Short, We

Hi there, to cut a really long story short, we lost our 18 week twins on 22nd July. The coil broke my waters, which initiated labour. It was a vaginal delivery, and had to have an operation to manually remove my placenta. My first period was quite light, my second period wa extremely heavy and third period was medium. Before my third period I had some light spotting, and a week after my third period I have started to bleed more than spotting with some small blood clots. I have a chest infection currently (been a two weeks as of today) and am coughing very hard, but is beginning to ease. I wondered if this could hVe anything to do with it. Thank you.
