Hey ladies I did my first round of progesterone where I start taking it on the day of my positive ovulation and I continue taking it till my period starts. Well my period still has not started I’m now 4 days late going on 5 and my breast are killing me. Is this normal? I was told that progesterone would not delay your period and if it did it would only delay it for a couple of days by my obgyn. So now I’m 4 days late I’m cramping like AF is coming my back hurts Iv got cold like symptoms and my boobs just started hurting this morning. Two negative pregnancy test so I know I’m not pregnant. Any thoughts?
