I'm 37 and ttc my first child. I have just started using the clearblue digital ovulation test. We dtd this morning at around 7am but I have only just tested at 12pm for today and have had the first solid smiley face. Do we need to dtd later today or is tomorrow best? Sorry I'm clueless. I just want to get pregnant so much and don't want to miss this first window of opportunity!
