Advice please

Question. I'm taking clomid, progesterone, and took my Hsg Shot on Monday. Today is cycle day 16 where I'm supposed to take progesterone. I've been taking progesterone for almost a year this is my first month taking clomid and the HSg shot. I thought I'm supposed to do the waiting game and see if anything happens this month and then start progesterone again next month if my period dont come. I asked if its ok to take that just in case I did get pregnant. Question is has anyone taken all of these three things and still became pregnant and was everything okay. I asked him that question he said yes. Yes I do trust my doc but hope you ladies know what and where im coming from.
