Nausous around ovulation?

[ZigZag]

I'm new to charting but have been TTC #2 for 3 cycles now, and have noticed I get quite nauseous just before and on/around ovulation. It comes and goes over a day or two. Just wondering if anyone else has a similar symptom and if you think it's normal?

I recently lost 15kg (over 4 mths and still losing gradually) and my cycle has changed a little bit and is still slightly irregular (by 2-3 days, is that considered irregular?), so just wondered if my body is still adjusting to a new cycle with the nausea I experience?

Thanks
