My daughter (2y/o) non stop asking me for a brother or sister like 🙄🙄🙄 m’am I’m trying.

We had sex on my ovulation day and I’m a little tempted to test. I’ve been super tired. In that nesting mode like cleaning and getting things ready? If that makes sense. Not that I think I am or I am not, I’m just organizing like my life depended on it. I was super super nauseous the other day like horrible with a head ache and all but not my regular head ache. I want to test but I’m a little shaken by my miscarriage last year and then on top of that I tested last month got a positive and then a negative. I guess a chemical pregnancy… I’m just scared honestly slightly discouraged.
