Weird cycle...just need to vent

AW • Wife. Mom of 2 💗💙.
Quick background - went off the pill 9 months ago, trying for 3 months now, my cycles are normally 35 days, never had a positive opk (using them for the past 3 months) only ones that are dark but not totally positive.
This cycle I found out I am hypothyroid and started medication about week ago. Prior to starting tr medication was supposed to be my fertile week, but I didn't get any ewcm or cramping like normal. Instead my nipples really hurt. A few days ago, after starting the medication my chest hurt so bad. I was supposed to get my period yesterday and still nothing. Tested and BFN.
This cycle was so weird I am wondering if it has to do with the thyroid...what if I don't get my period? I was thinking about starting vitex - when should I?
