Not pregnant this month?

We had another miscarriage last month and we were TTC but not religiously (my mental capacity is at its limit so I’m not super in the mood every night) but we had sex every day in the lead up to ovulation and on ovulation day. My period is due in 3 days but obviously I’m an idiot and have been taking tests since 10dpo, all of which have been negative. I’m now 13dpo and still nothing, should I admit defeat and accept I’m probably not pregnant this month? I’ve had the usual light cramps and fatigue but that’s also a sign of impending period. I’ve been pregnant 5 times now (1 living child) so I’m aware of the signs to look for, realistically should I just accept it’s not happened this month? Feel so resigned to the struggle of conceiving 😔
