I'm a fit and healthy early 20s female, obviously.

I've been feeling "off" the last few days, nausea, tired etc. Last period was 11th of June 2020, I'm three days late. My cycle is regular and last roughly 23 days. Is it too early to take a test? I took one this morning but it came up negative.

Thank you, please be kind, mixed emotions right now. My partner and I are trying!
