Help- clomid short cycle

Hi girls :),
Just wondering if anyone has experienced this .... I have just finished my 1st cyle of clomid, l did ovulate but it was missed by everyone as l ovulated very early (while still on the clomid) then today, day 14 l have AF. I usually have 50 day cycles so you can imagine this has been another surprise. The ART nurse today said that l have a problem with shortened luteal phase and will need to take progesterone injections to assist the luteal phase and hopefully a bebe. I am feeling a bit stressed about it all as it is another intervention and like so many of us a MC is my greatest fear. On the otherhand l feel blessed that there is a medication to assist and l am early in my journey of assisted conception, so l guess it is all information gathering. I just never thought this would be happening to me or that having children would become such clinical situation.
Thanks for reading :pray:
