Hi everyone. I've been off my birth control pills for 6 months and, since then have had extremely regular 29-30 day cycles with 4-5 day periods. Until this month. I am now on day 33 and still no period. On day 29, I got period-level cramps and spotting (which I  don't normally get) and that lasted about 3 days, but then that just fizzled away into nothing! I am 100% sure I am not pregnant. Also, just a few months ago I had a pelvic ultrasound done (for something else) and it came back totally normal. Is it possible to just have one wonky or missed period occasionally? My husband and I would like to try to conceive relatively soon and I don't want any hitches in our plans! Anyone else ever just have a crazy period on occasion? Thanks!
