need some help deciphering symptoms

Autumn Kay • ttc since 2014. had a miscarriage 7/2/16.

Okay I'm on CD 35 and I don't think I ovulated when glow says I did, if I did at all. But I've been feeling like af is coming for over a week now (cramps, sore breasts, heartburn. all is abnormal for me before a period ) and just had very very

light spotting on CD 30 and 31. Af is irregular so I'm not sure when I'll be officially late. Do you ladies think I'm out this cycle or when should I test? I'm just starting to get back into this TTC thing.
