After ovulation estrogen is joined by progesterone from the corpus luteum making the endometrium denser and mature. Estrogen is not only metabolized by the liver but also re-circulated between the gut and the liver (entero-hepatic circulation). Antibiotics can affect estrogen metabolism in two ways. Most antibiotics are metabolized in the liver and their presence can affect the rate of metabolism of estrogen (and progesterone). This can change the supply of estrogen available in the blood and that can cause irregularity of the cycle. Some antibiotics cause diarrhea like symptoms as they change the gut flora.
So yes the progesterone could be delaying your period, or you could be pregnant. I've found when first using it, bleeding can be either later or earlier than normal, it does settle in time.Progesterone does raise temps, but it's impossible to tell if yours is higher due to the 400mg/day you're using, or pregnancy.y doctor has told me to take 200mg 2Xs daily from day 20 until my period begins. I have very regular cycles (to the hour) and have seen a lot of info that progesterone can delay periods (I'm taking Utrogestan).
