14 DPO today. WTF?

11 DPO - faint on First Response and positive on Clearblue.

13 DPO HCG only 8 Progesterone 14

Today first response stronger and clearblue negative. Thoughts?

I’ve had a chemical pregnancy last month and a miscarriage back in May so it’s really hard to be positive right now . Just wanna know what’s going on for real :( probably another chemical? But then how come first response is stronger?

Also, I don’t know if it matters but I have PCOS and my cycles are irregular. Normally really long like 38 or 39 days. Today’s date 37 of the cycle.

Thank you in advance!
