Chemical.. Again...

I have two daughters. I had 2 chemical pregnancies prior to conceiving my first daughter. I have been NTNP for over a year now while trying to get my cycle back to normal (bc screwed me up 2 years ago). Period was due the 20th, was having some familiar symptoms. I had a feeling I was pregnant so I tested FMU on the 20th (yesterday) and got a VVVVFL that showed up instantly. I was ecstatic but decided to test again in two days. Woke up this morning to blood when I wipe, light pink and only when I wipe but it’s been fluctuating throughout the day to darker red and small clots. Unsure if the positive was a fluke and this is my period or I had a chemical 🙁
