Clomid and trigger shot! Help please!

Natalia 🧡
Hi, this is my first cycle with Clomid and I really don't have any clue. 
I've started clomid on CD4 for five days.
On CD12 the doctor saw a nice size follicle so told me to have a trigger shot the on CD13 at the afternoon, which I did, at 17:30. He also told me to BD every other day from CD14, for a week.
CD14 was an awful painfull day. I cramped so bad that I can't even walk straight. So I take a Tylenol and manage to BD at night when the cramps were less intense.
Today, CD15, I'm painless and my bbt went from 97,34 to 98,06 since yesterday.
This means that yesterday was my OD? I'm pretty confused, the Dr. says that I have to BD o every other day for a week so my next BD should be tomorrow. 
Help me, I'm super confused, I need some advice! Thank you and sorry about my English, I'm not a native speaker.
