So LOST! Help!

Sooooo I’ve started Clomid on the 1/30 and do Saturday is when my period is supposed to start and we will see... but I’m worried because the doctors office called today and said my progesterone levels are low (they tested Friday) and so i did some googling and it’s pretty much saying that IF I am even pregnant it’s gonna be lost.... but I could swear that I am..... my boobs are more sore than ever before I have this pressure feeling between my hip bones in the entire area and it’s not gas but gas and having to pee make it worse and can sometimes hurt if to much pressure... and this pressure thing started the week of ovulation... I only had about 3 days total left of ovulation and that night it kinda hurt having sex nothing to bad tho... then the next day I was sooooooo sore... if I coughed,laughed, or stepped to hard it was like I was jarring something and it would hurt like sore muscles.... I’m just really confused it’s hard to tell what ovualting normally is like verses when u ovulated and might be pregnant.... please help! Thanks in advance!
