TTC and unsure

Sacia

My husband and I have been trying to conceive for over a year. I have 2 kids from previous marriage as does he. So we know we are both able. I ovulated 10 days ago, and am due for AF in 4 days. I have taken 2 tests both being negative. But I’ve been nauseous and breaking out, both uncommon for an upcoming period. Am I testing to early or is this another uneventful month? TIA
