definitely way too early for pregnancy symptoms if you aren't due for AF for another week.
it wasn't as heavy as usual but it wasn't really light and it didn't last as long as normal
Normally I would say yes, they could be signs of pregnancy. But I'm wondering, if you're not expecting your period until the 26th, if you didn't just ovulate about 5 days ago? In which case you wouldn't have any symptoms yet, let alone for two weeks. UNLESS, your last period wasn't really a period and maybe you've been pregnant for an extra month! Who knows? I had a friend who had 3 periods while she was pregnant! I would say wait until closer to the 26th to test. You cold use one of those "early result" tests 5 days before your period. Did your last period seem weird at all? Like shorter or lighter?
