Okay, so AF was due Monday, and it didn't happen. Nothing Tuesday either. I tested Tuesday afternoon and got a feint line (I wasn't the only one who could see it, so I wasn't imaging it!). It was feint, but showed up straight away and was pink (first response brand). I was shocked to see a 2nd line and tested again Wednesday morning (FMU) to confirm either way, but got the exact same feint line. Wednesday evening AF arrived, I tested again and line was gone.

Now I am clearly not pregnant, so what on Earth caused the 2nd line? To the best of my knowledge the only other cause of a 2nd line is an evap line, which is grey and shows up after ten mins. Are there any other 2nd line causes I don't know of?

Edited because I didn't realise this forum was a subset of TTC
TIA!

back*again, it is possible that you were pregnant and have had an early miscarriage, which at this stage would be called a chemical pregnancy.

[noi'mnot]

Perhaps you had a dodgy batch of tests.

Perhaps you had a chemical pregnancy, or an early miscarriage, meaning that you had the hormones in your system but the pregnancy wasn't viable and ended in a period.

A few women do bleed in a period-like way when pregnant, so you should probably test again. It's also probably worth talking to your GP and letting them know what happened. If it was a chemical pregnancy or early miscarriage and you're not trying to conceive, perhaps you might want to look at the contraceptive option that you're using to make sure you're better protected.

Good luck!

I would say a chemical pregnancy. The problem is with pregnancy tests is you know you are pregnant before they embryo evens hits the uterus as they are so sensitive.

I hope you get a sticky BFP soon.

hCG is produced when the cells of the placenta attaches to the lining, not before.

Please explain? When does the placenta attach?

[silver-rain]

If you are pregnant, the fertilised embryo will implant into the uterine wall between 6 and 12 days after ovulation. It is not until this happens that it starts producing HCG in quantities high enough to be picked up on a HPT.

for the record, I had an experience almost exactly the same as yours in January, my AF was late ( and it's never late), but I was only returning faint lines on 3 consecutive HPTs. The next morning, the HPT was negative and Af arrived 3 days late. I put this down to a chemical pregnancy too.

Sorry OP, sounds like a very early (chemical) miscarriage.

I thought hcg was produced from the corpus luteum until the placenta is developed enough to sustain the fetus by itself?

[carriesshoes]

Yep - chemical pregnancy. I've had one too.
Apparently there is quite a high rate of these (approx 1 in 3 or 4), but because most people dont' test before their period is due they didn't know that they were pregnant and just have a period that's a couple of days late. It's only us that are active;y trying and have the patience of a flee that test early and get a positive that even know it happened.

This The cells that attach to the uterine wall essentially become the placenta.

The corpus luteum produces progesterone, not HCG.

Also remember that implantation is a process that occurs over about a week rather than fingers snapped, it's done
