TTC after MC - shooting pains

Billie • TTC after a misscarriage in June and December 2015
Hello! 
I am TTC after 2 early misscarriages and have now started to log symptoms, CM and cervix.. According to glow I am in my fertile week and have sharp shooting pain in my vagina/Anus (nice!!) 
I makes me wince but doesn't last long. 
I wondered if this could be linked to ovulation? 
Anybody else experience this? 
Thanks xx
