Any similar experience?

Hello. My lmp is Aug 12. Actually my menses are super irreg and I am diagnosed with PCOS since 16yo. After 8 yrs of negative PTs, nung wed nagtry lng ako mag PT pero no expectations at all. Nasayangan lang ako sa PT ko kasi but it turns out to be positive. My first positive PT ever. However nagworry lng ako kasi since I don't know na preggy ako, active parin ang lifestyle ko and even drank soju (yun kasi bonding namin mag asawa), we even had covid ng aug 18-aug 30 😅 Nagpascan kami kanina however sac lang ang nakita, based sa size daw ng sac, baby is approx 5w 2d as of today, 10/15. Normal lang ba sya na hindi tlaga makita? Pinapabalik po kami after 2 weeks. All my lab results are normal and nagulat din ako kasi normal ovaries din ako, sanay nadin kasi ako na pcos lagi ang diagnosis. I am still at peace but somehow I want to know if this is really normal for mommies who are very irregular. My OB even laid out all the possibilities. Kapag ba walang baby sa loob, nagfafade din ba ang line sa PT katagalan? First time ko po kasi, thank you so much!
