Testing 4 days early.

So we started trying in August, had a miscarriage in December at 7 weeks, then have not conceived since then.

I’m getting impatient and I’m due for a period this month in 4 days. I did an early detection digital test and a cheap o test yesterday and both big Negatives. Not even a faint line.

It just stinks bc I have a feeling I am not going to be pregnant again this month and I’m devastated.

My question is, has anyone who tracks their ovulation and has a regular period cycle not get a positive stick till day of expected period?
