Trying to conceive

j
Hi Glowers! Been ttc for 12 months baby #1. 
Lmp was May 8-11
Fertile from May 18- 24
Ovulation (according to the web) may 23
Tried on  May 20 and 21 
There's is 9 days before my next cycle and I now have dull cramping pains which I usually feel 1 day before my period... I've never cramped this early on.... Has anyone gone through this ? Positive or negitive ? Trying not to get my hopes up but.... Wishful thinking
