Have you ever done chlomid w/NO IUI?

Shannon • TTC baby #2 for 6+ yrs. Healing from mc 3/15. We have 1 precious boy & his hearts desire is to be a big brother...
We were originally going to do chlomid with <a href="https://glowing.com/glow-fertility-program">IUI</a> this cycle but hinges have changed. It's not going to work out to do <a href="https://glowing.com/glow-fertility-program">IUI</a> but I've gotten the chlomid. Should I rely only on glow for prime fertility/ovulation dates or should I use OPKs? Or will the OPKs be off due to the chlomid? Thanks for the tips. XOXO
