It happened to me, I do happen to have the weirdest things happen to me. Anyhow, it was spotting, you have to call your doctor as soon as possible! Although my son is 3 year old now and I had spotting every month like this, it does not mean everyone will be as lucky as me. It can be reason to worry, nobody will worry more than you will for your baby. Don't believe the words "everything will be ok" all the time, sometimes things are not ok. Good luck, wish all the best to you and your baby.
