My period is due tomorrow i was 2 days late last month with little to no flow this month spotting brown a day before af actively trying to concieve could i be pregnant?

Possibly: It's possible, and easy to check. Take a home pregnancy test. If positive, congrats! if negative, repeat about a week after a missed period to be sure.

Possible: It's possible. I'd recommend taking a home pregnancy test if you do not get your period in the next few days. However, there are a lot of other reasons for irregular periods, so if it continues you should see your doctor.

Yes: Very possible, so get checked with a pregnancy test and if not pregnant, then make sure the cycle gets back on track next month or else see the gyn specialist.
