Missed period

shayla

So this is my first post so I don’t know all of the terms but my bf and I have been TTC for about a year now. I am 13 days past my expected period date. I spotted for two days around the 5th of September but I’ve taken two at home tests and they are negative. I am usually very regular at 28 days. I have never missed a period without being pregnant. Is this just a missed period ??
