ok ill start 2 months ago. anyway 2 months ago i took the plan b, and my period that month lasted 7 days, but was on time. last month i got a period that lasted from the 23rd to the 26th (more accruate 23rd noon to 25th a little after noon and absolutly no blood in me by the 27th. not sure if it stopped on the 26th or not if it did it was extreemly light) now the blood was normal color and was just not as heavy flow as normal, now this month on the 22nd i should have gotten my period but its now the 24th and no period, i had normal PMS symptoms like headeache acne breakout and bloating but still no period, do you think i could be pregnant? if so would it have been last month or this month that i became pregnant?
