So, if implantation happens on average on 9dpo, then with IVF pregnancies it happens on 4dp5dt: 4 days after a 5-day embryo transfer or 6dp3dt which is 6 days after a 3-day transfer. As hormones change, many women begin to experience common symptoms of early pregnancy such as fatigue, nausea, cramping, and breast changes. Any changes you see at this stage are closely related to what you might see before you get your period since progesterone is still high at 9 DPO and the likely culprit of many symptoms.
