LMP 30d: So your last period was about 30 days ago. It's a little early to detect if you are pregnant, at least with home testing. Your symptoms don't sound that suspicious for pregnancy. If this does not bother you too much, give yourself 3 days or so. Perhaps the period will still come? If not, it is a good idea to do some pregnancy testing.
