I don't mean to sound rude, but you seem to have an obsession with posting this question. This can lead to an increase in anxiety for you. RELAX. Everything is fine right now. If she gets a positive pregnancy test,which is very doubtful, then worry about needing help then. Also, I have posted a response before. I'm not sure why you keep asking the same thing????
This guy has been posting the same question all over the forums, I believe he may be a troll.
She can't get pregnant from that! Im 100% sure you can calm down.
Sometimes if you are stressing or have stress, it delays the period. Is she regular in her periods? If she has taken two home tests and they were negative , then you guys should be fine. I would say for her to relax if she is stressing and if she does not get her period in another week then maybe she should go to the doctor for a blood test to confirm it being negative. Good luck!
