Hi cadokat,
I sincerely hope that everything is ok and I'm sorry for your loss.
I also had an early miscarriage (chemical pregnancy) 2 weeks ago (9 June), I was 5 weeks too. Then I had unprotected sex on the 6th day of bleeding, however it had slowed to spotting. The next day the bleeding had stopped completely. I then had what looked like an implant bleed on 17 June and ever since all my pregnancy symptoms have returned. I took a hpt on 22 June but it showing negative. I will take another this Fri 26 to make sure.
Just because you are not experiencing preg symptoms doesn't mean you aren't pregnant. Did you experience symptoms prior to your miscarriage? Every pregnancy is different. Keep in mind that a lot of women don't actually experience pregnancy symptoms until around 10 - 12 weeks. Some however experience symptoms as soon as they conceive. If you tested positive at the Doctors and they confirmed that you are 6 weeks along then trust that. If you are still unsure due to you having a period like bleed then go back and ask for a re-test. Was the period a heavy one or a normal one?
Just out of curiosity, did you have an implant bleed with your current pregnancy? How long did your miscarriage bleeding last for? Finally if you count the 1st day of your miscarriage as day one of your cycle, on what day did you ovulate?
Sorry for all the questions. Please PLEASE keep me posted as to what happens. My thoughts are with you. Big hugs xo
