Faint positive 9DPO

I had a faint positive 9DPO and have since tested faint positive again at 10DPO and today (11DPO). I had a MMC last year and we had started our IVF journey and have conceived naturally. Just wondering if anyone else had faint positives before their period was due? Trying not to worry, but after our last loss I’m just scared! Have put yesterdays test in comments Thanks! 🙏
