Ttc after miscarriage

Can I do a pregnancy test 8 days before period ? I really want to know if I’m pregnant, I was pregnant in February of this year with metformin and a fertility meds. But I had miscarriage at 17 weeks and I really want to know if I can get pregnant this time without fertility meds. I have PCOS.

I’m so curious to know if I can get pregnant this time without fertility meds. I had intercourse 1 day before ovulation and 1 day after ovulation. I followed the calendar n did it.

I’m so eager to do pregnancy test in next days. Please advise. Thank you.
