Some examples of substrates used (also known as chromogens) are AEC (3-Amino-9-EthylCarbazole), or DAB (3,3'-Diaminobenzidine). Use of one of these reagents after exposure to the necessary enzyme (e.g., horseradish peroxidase conjugated to an antibody reagent) produces a positive immunoreaction product.
1. Know When You Ovulate after Childbirth. Most women experience an extended period of bleeding immediately after giving birth. The bleeding will get lighter and lighter, lasting about six weeks. It is extremely unlikely that a woman will become pregnant during this time, although it is not impossible.
Generally speaking, about a day or two after you give birth, the uterus will be about the size it was at 18 weeks and will get progressively smaller over the following days. Youâll probably feel cramping or abdominal aches and pains in the weeks after the birth, especially while you nurse if youâre breastfeeding.
