Possible hook effect?

Brittany

Hi everyone! I'm new to glow and after abit of advice..

I had multiple positive tests and my initial hcg reading was 13.

I did have a 5 day bleed but it started off light, got medium then dimmered down again, not norm for me at all.

Hcg levels were done after the bleed. I have had no further bleeding

And my frer tests continued to get darker.

Now, from research and what people have told me; if you misscarry lines will not get darker they will actually get lighter till they are negative. Except mine did the opposite. That is till 2 days ago. It went from blazing bfp to very light line not even a gradual drop. Just blaring bfp, then very light the next day.

Im still now getting the same colour light lines and still have most symptoms.

I dont understand why this would happen.

The doctor told me to keep the tests to show . progression. Having bloods drawn again in the morning.

Any experiences, advice etc muchly appreciated!

I would be around 6 to 8 weeks not 100% sure.

I had positive opk on the 10th of april negative opk on the 11th.

Avg. 37 day cycle, avg 16 day luteal phase.

And have been taking 1500mg metformin daily for.4.months now.
