ovulation cramping?

Courtney • 👼🏼 2-26-17 and now our Rainbow baby is here! 6-2-18 Carter Logan Freeborn 🌈👶🏼 and Easton Kent Freeborn due 7-26-19
The last two days I've been feeling slight cramping on my left side. I haven't been tracking ovluation or anything like that because I have irregular periods. I finally had a period on 1/15 and it ended on 1/21, so we've been trying again for baby #1. According to Glow I just started my fertile window on 2/1. Any and all opinions would be great! Also just started using pre seed two days ago. Thanks in advance.  💕🤞🏽
