TTC #1 second cycle, gutted as I really thought I was pregnant had all the symptoms and I'm sure we dtd for three consecutive days once I was ovulating. Only came off implant in Jan and my periods come back Instantly so just assumed I'd be pretty quick. Trying hard to not worry. I've looked back and we didn't dtd much before my predicted ovulation so I'm thinking need to do it more beforehand this time. I've read about the SMEP method has anyone done this before and had any success?
