Possibly further along then I think..

So April 12th I went to the ob for a regular yearly pap and she was pressing on my stomach after the pap she asked me to take a pregnancy test because I told her about my boobs being sore and a little bit of nasiousness sure enough it came back instantly + w/o a doubt at this day according to my tracker I would only have been 10 dpo, I didn't take a test on my own because I had the same tender breast and tiredness in March when I tested around the 17th and got a negative and I had a period on March 19th or 20th so April I blew off the symptoms not thinking anything of it until I went to the doctor and she told me I most definitely was....so now I'm curious as to if I'm 6 weeks according to my last monthly or if I'm further and really was pregnant in March and tested early? has anyone else had this happen? I have a 6 week app. Friday and I can't wait. I feel like I am severely nasious and wanting to run to the toilet constantly more then I should be at 6 weeks. If I really am 6 weeks I'm going with it has to be twins lol
