I went in for my first ultra sound because I insisted that they do it since I didn’t know how far along I was (I’m irregular) I’ve had faint positive lines for the past 3 days and at the doctor there was also a faint line on the urine test (sooo faint) then when they did my ultrasound right after they showed me what looked like a dot and said that it looks like my baby sac but they weren’t sure because they think I’m way to early to even do a ultrasound & since I’m showing up super faint positive she said that I might be JUST 3 weeks and with 3 weeks pregnant it’s hard to see anything they want me to come back in two weeks.. im a little nervous has this happened to anyone before? Tested again today and the faint line become a tad darker
