period late

Kaylee

I'm on day 31 of my cycle. I usually have 28 day cycles, but my last one was 25 days. I've had watery/creamy cm for about a week, and no sign of my period yet. I have a 15 month old and I've had about 6 or 7 cycles since I had her, all between 25-28 days long. My husband and I use condoms but only at the end. should I take a test? I'm starting to think we might have made an oopsie lol
