period after pill won't start 😭

Hi all, my other half and I decided to try for a baby in late Jan early Feb. I came off the pill on the 8th Feb and we started trying straight away. While I was on the pill I still had a period every 28 days. My period was due on the 22nd Feb and I'm still waiting for my period to start!!  Anyone got any recommendations or advice on how to get this period to start sooner?!
