HCG picking up LH?

Ok so long post...sorry in advance.

So on July 10 and 11 I took three different pregnancy tests. They all showed some faint lines. Then retested this past Thursday and Friday expecting darker lines.

I had my last period on June 25-29. It was weird and shorter and lighter than normal. Well when I tested on the 10-11 I thought maybe I had ovulated weird. Now I’m guessing that I am supposed to start like normal on July 25th. Anyway, I took two more tests this past Thursday and Friday and BFN.

No period signs. Boobs feel heavy and I’m super tired, I had three days where I have been ridiculously nauseous and irritated. Now all symptoms except constipation and tiredness have stopped. I’m very bloated! Like unusually bloated. Creamy cm.

Just wondering if maybe my faint + earlier in the month could have been picking up LH instead of hcg. Also I have two kids and have been feeling that stretching feeling in my low pelvis. It’s an unmistakable feeling. However, BFN. I plan to wait and retest

again on the 26th. Just wanted to see what everyone thought. Sorry if this seems all over the place....haha!

These were taken July 10-11

These were this past Thursday and Friday

Thank you ladies!
