So I am due for my period next Thursday and I really hope it comes on time considering I had a lap 2 weeks ago. After my first lap, I was four weeks late so missed a whole month! I am getting nervous as we are going to try naturally for 3 months, sounds silly hey?! I didn't use OPK's before all of this IVF stuff but do you reckon they are a good idea?? I want to make sure I am doing everything possible.
