Hi everyone. I had my embryo transfer on the 5th December and was feeling ok up until the 8th and 9th of Dec. I now feel like I am about to start my period within the next few days and my pregnancy test is not until the 18th of Dec. I am having all the symptoms I usually have a few days before my period starts, exactly the same feelings, cramps, tenderness in the pelvic area, feeling a bit fed up and irritable. Has this happened to anyone else and has anyone had their period before the pregnancy was due? thanks
