D and c, irregular period??

I had a d and c done on May 19th due to a blighted ovum, got a very light period on June 24 that lasted 5 days. Before my d and c I was regular. Would a d and c throw off my cycle? I'm praying we conceived! I have been feeling extra tired, and getting headaches which is unusual, and have not had an appetite at all. Has this similar situation happened to anybody? Any comments are appreciated!
