Can't remember where you left your keys? Or forgot a task which needed to be done? It can be frustrating at times but dont be harsh on yourself. Its got to do with the hormonal changes you are undergoing. This phase is called "momnesia" or pregnancy brain. What you could do during this time is relax and try organising your day - write things down, or set reminders on your phone, delegate tasks to hubby dearest and to those who don't mind giving you a hand. Don't worry, too much about this phase as it’s temporary — you'll have total recall again.
