I miscarried at 5/6 weeks last month and we are desperate to try again. I'm confused as to what my body is now doing and opks appear to be teasing me. Are any of these positive? They've been on off like this for about 5 days. I am seeing more lines consistently from last night-now but have no idea at all what is happening. I also have cramps which I've had for quite a few days however these feel different to any cramps I've felt before I'm on CD21.
