Vvvvv faint positive after ten years TTC scared

[TTCbaby1soph]

Hi,
I’m approx 16dpo today predicted using OPKs. Yesterday I did a Superdrug test which showed a vvvvv faint but coloured line and then did two clear blue week indicators which said not pregnant. They were both with afternoon urine.
this morning I saved my FMU and got boots ealry detection which are more sensitive and again is showing a second line but vvvvv faint. I’m really worried the lines should be darker. I’ve never ever even had a squinter of a positive test before in ten years TTC on and off !
also in past day 21 blood tests I have always had low pregesterone should I be worried about that? The only thing I’ve changed last 3 months is I went on Keto based and then switched to carnivore diet.
im so worried I don’t know where to start or what to do. Please help ! 😭😭😯🥹😂
never seen a line in my life.
also been reading about possible late implantation but all seems to be negative. Is it still ok to have such a faint line at 16dpo

Hi, so sorry you've had such a long fertility struggle. I had my boy via ivf so I know the pain of month after month of negatives or faint positives that turn into nothing:(

At 16dpo if you got the dates right, a fertilised egg will have left the fallopian tube and made an attempt to implant now. It takes about 5 days to exit the fallopian tube so 11 days to implant and still only produce a tiny amount of hcg to show up a faint line doesn't sound viable I'm sorry, but your dates may be behind a bit and it could be the start of something. I got a few faint pink lines on those thin strip tests you can buy lots of on some cycles then my period would come anyway. The clear blue digital ones that say pregnant or not pregnant need lots more hcg, can you try a first response early response test? That was where I got my earliest positive.

Low progesterone can indicate you aren't ovulating every month, or that you have low progesterone despite ovulating. I had the same so for ivf I had to have double the progesterone support to give the embryo a chance to implant and then carry it to 12 weeks.

Really hope this faint line becomes something and the dates aren't exact, fingers crossed but if not definitely look into progesterone support or why you have low progesterone.

Even if this does not lead to a pregnancy take it as a positive! You Said you had never had a bfp in 10 years? Even if this is a chemical something is changing in your body which could be your egg quality is improving thanks to your new diet! Keep up your new diet for sure and what ever this leads to see it as a good sign
