So my last period was Jan4-9. I track my period religiously and it's is very regular.. My normal range is every 34 days and I don't miss periods.  I also track my ovulation for the most part. With this last period I believe I ovulated on time on jan24th. I had unprotected sex the night of the 23rd going into the 24th🙈.. my next period was to come Feb 7th... coincidentally I'm 6 days late. If I am pregnant should I have still gotten this period and missed the next or conceiving should have definitely made me miss this period so soon. At this point I'd basically be going on 3 weeks pregnant. Is it also possible to have symptoms this early?
