Need advice!

I just need some input on what y’all ladies think. So I started my period on April 29th it was brown as it always is when I start. On the 30th I had red bleeding but not even enough to fill up a pad over a 12 hour day, later that night I put in a tampon. When I woke up on May 1st I took it out and there was only a little bit of brown, barely noticeable. At this point I thought I was at that break in my period where it slows down then picks back up. My husband and I went to dinner that night and when I got home I took my tampon out and it was completely dry. So at this time I put a pad back on because I was just confused. I have only been spotting brown for the past 2 days and around 6pm tonight there has been nothing in my pani liner. I had a miscarriage in February. Last month my period was 9 days long. I am making an appt with my gyno on Monday but just wanted some advice or input until then because I’m so confused at this point, I’ve NEVER had a period like this. The only time i had something similar to this is right before i found out i was pregnant in February. pregnancy is a possibility but I took a test this morning and it was negative.
