Period Changes

Kate
I've never spotted before a period in my life before. Last month I spotted for a day, then started my period right on time 4 days later. I'm due for my period again. Today is cycle day 32. I spotted yesterday morning, but I don't even know if it was actually spotting. Just light brown discharge on my toilet paper. I figured my period was coming so I put a tampon in. One brown spot on the end 6 hours later. Nothing overnight and nothing this morning. What is going on?!
We only started ttc in February, so I know this isn't long enough to think about fertility issues but it's freaking me out that my cycle is changing. I've never had fertility issues before. We didn't plan our other two. I suspect I've had one very early miscarriage before, but I don't know for certain. I have to say "figuring it out" is preferable to stress and disappointment. 😒
