Trying to stay positive

Tia • 30, married to my best friend 7/5/15, My 💙 Jaxson 4.14.18
Hi! I'm 26 and I've been married for two years, ttc for 6 months. I was not ovulating on my own so my doctor put me on clomid, estradiol and progestrone the first cycle. I have since gone up to 100mg clomid and 200mg progestrone pills. I started a day late this cycle (cd 4-8) and received a solid smiley on the clear blue advanced on cd 16. My doctor says to start the progesterone on cd 18. I'm wondering if this is too soon because I read that progesterone could possible stop ovulation. On cd 12 I did get good news on follicle size and how many but I haven't felt any of the ovulation symptoms like I normally do since starting the treatments. I am trying to stay positive and praying during this two week wait. I just want to talk and see what you guys thoughts are. Every time my AF comes I get in a bad head space, especially because two of my close friends found out they were pregnant. Hope I used some of the terms right lol. Currently cd 19 and I think 3 DPO.
