This is my first month TTC. I O'd on the 15th. DH and I BD on the 14th and haven't since then. I'm pretty sure I'm 3 DPO today and I've been experiencing strange twinges. I'm have cramps similar to AF cramps but it's still different. I have no appetite an have to make myself eat. Do you think there's any possibility I am pregnant? Has anyone experienced similar this early after O? I know this could be all in my head so I'm not getting my hopes up, I was just curious.
