Hi fingerscrossed it sounds like you have suffered chemical pregnancies - sorry to hear this has happened to you twice, it is a really crappy, disheartening thing to happen. From what I understand of it it is when you conceive but implantation doesnt occur. It usually means the pregnancy isnt viable and it is sometimes described as a very early miscarriage before anything could have been picked up on ultrasound - although I have only ever read that term online and never heard it mentioned in rl.
I had a chemical pregnancy a couple of weeks ago. I got a faint positive 5 days after my period didnt show up and the same day a digital confirmed pregnant 1-2 weeks. However the next day I did another dye test and it was even fainter. I saw my gp a couple of days later to see what was going on. She did her own test which came back positive a couple more days later and I was obviously delighted. Then two days after that I started bleeding.
I had what should have been my appointnent to discuss my positive result but had to tell her I no longer was. I was lucky in a way because I had it documented as a pregnancy albeit a shortlived one, but from what i've heard, some women barely have it acknowledged which can be hard if like me it felt like a loss to you.
When I saw my GP on Monday she told me it was very very common and that it is not a sign of anything being wrong. In fact she said it is a good thing that your body recognises that something is wrong in the pregnancy and that you are able to conceive. She said that some women would never have noticed and it was only because I knew my dates.
I asked how soon I could try and she said wait three months!! I was shocked and asked why and she said to just give your body time to heal and because they would worry about anaemia and "things"...although didnt have a precise answer. I pressed her further later in the conversation and asked if I really had to wait soblong since it had happened so early and she said that the nhs are just cautious and that where she comes from (she is Indian) women lose a baby and try again straight away, get pregnant and are fine. She then ended the conversation telling me to eat an drink well, rest, and try again when I wanted to. So I think really it is just standard nhs guidelines after pregnancy loss.
I am trying again this month. Good luck whatever you decide to do
