I’m wondering when I should take a pregnancy test to see if I’m pregnant this month. I took an OPK on the days denoted with the check marks (29th & 30th) — it was negative. I also took a pregnancy test this morning and it’s negative :( my husband travels for work so idk if we are having enough sex

Ps, I know the test I posted is negative, I’m asking based off my calendar when should I be testing?
