Pregnant after chemical

Had a chemical pregnancy around 5 weeks in the first week of February. My bleeding lasted 2-3 days longer than normal. I now have a positive test again - which is amazing and I’m so grateful. But I’m also really nervous because I’m now one day late and the line is really light. Last time I got a positive on first response 5 days early. This time I didn’t get anything until the day my period was due. Did anyone else have a chemical and it messed with their cycle? I’m also wondering if maybe last time I implanted early and this time I implanted late? Anyways, if anyone has experienced this before please let me know! I’m trying to be positive and relaxed, but easier said than done after last month. Thanks!
