Spotting During 2WW after IVF

Hi There,

I had egg transfer on Monday 20 April. On Sunday 26 April I started having very slight dark brown spotting vaginal bleeding. It has continued on and off since then. The spotting has been extremely light. Only noticable when I insert pessaries, or slightly when I wipe myself. In fact, yesterday it was extremely minimal.

Also, I have had cramping too although this has eased off. Not bad at the moment but can still feel sort of achyness. It felt like cramping before AF due to arrive.

My pregnancy blood test is Friday 1 May.

Does anyone have any suggestions what could be causing this, and I would appreciate your sharing your experiences during this 2WW period.
