I’m so upset

I started spotting brown at 1dpo and it’s continued ever since. I’m now 10dpo. Got a faint line on frer this morning. Definitely there. Also confirmed with a faint line on wondfo. I had negative yesterday. I just started bleeding (it’s red) and this is only cd24 for me. My cycles are normally 28-29 days and are typically completely normal. Why is my body being so crazy this month. I just want a healthy baby and I really don’t want to have another chemical pregnancy 😭
