I’m wondering how far along I am. Last period was aug 19th... not much of one very light period only lasted 3.5 days didn’t have to change my pad even each day. Wore a panty liner the last day not much at all. Could I have been pregnant then? Doctors won’t get me in until oct 8th. But wasn’t able to talk to the dr about it. Nurse didn’t seem to care or she was too busy. They think I’m 4 weeks I think I could be further along.
