My last period was aug 24th, and I missed for September I am now two weeks late.I have taken four pregnancy tests, the first was early on came back negative, I took another three days later and it came back with a faint positive. I decided to wait another two days and that one to came back negative, so I waited another three days and took another one. It was negative. I am two weeks late, and have every symptom possible of pregnancy ( I know because I already have two kids)if there is anyone who has been in a similar situation and has an answer to whether they ended up pregnant, please do tell I have searched everywhere and all anyone could tell me is ''go to the dr'' of course I know this!lol but in the mean time I would like some advice, and hopefully some shared experiences. Thank you :)

Go get a blood test from the doctor.. other then that I don't know my first pregnancy I didn't even know I was pregnant until she started moving

You may not want to hear it -but I believe you have two options: 1. Wait and take another test in a week, 2 weeks..
2. Go to a doctor! Good luck...
