Today I noticed that my female may be ovulating. I do not have a picture as she seems unusually cranky, but near the last portion of her body,there is a small but noticeable lump.
An ovulation is unmistakable, your BP will look like she swallowed a football, not a small lump and not located in the last portion of her body but in the mid section


But through all my research, shouldn't there have been other signs before her ovulation, like cool seeking and "lumping up" and "the glow before they go"?
Yes you should.

And another couple quick questions. Is it okay for me to handle her if she is ovulating
Briefly for maintenance yes it's ok but you want to limit stress and leave her alone until she lays.

And if this is an ovulation, do I continue to add the male?
No if she is ovulating she is done and will lay eggs in about 45 days
