Dude. At what point do the Bump Gods notice that a good chunk of these newbie accounts are obviously bots/spammers? They either post weird links or grammatically garbage sentences/questions like this one. There used to be a waiting period to avoid this nonsense.
The “experts” you are looking for are the ultrasound tech and the physician you see. What did they say? I would trust what they say over anyone else. We aren’t experts and don’t do gender/sex guesses here. If you are as far along as we all are, your provider should be able to give you a reasonable answer.
