CD 1... Next AF May 18th... Buddies?

LJ • Baby girl born Feb 19, 2015 and second girl born Jan 20, 2017. Baby #3 due in October!
26 day cycle, this month will use OPKs for the first time. Month 3 trying for first baby. 34 years old. I'm going to the doctor next week for a consult to ask about spotting and if she would recommend Clomid or any testing yet. If anyone has anything else I should ask her about, please let me know.
