Should I test!???

Hello ladies! So last month my period came on time (regular 28day cycle) LMP (6/14/2018)

Estimated time of ovulation was 6/27/18...I spotted on and off 9dpo-12dpo... “expected period should have came (7/13) according to my app... I have had occasional cramps here and there. A horrible pain on left side for like a short moment... and AF hasn’t arrived. I want to test but I don’t want to cuz I don’t wanna be disappointment 🙄 the struggle of ttc!! Lol
