Am I pregnant or not? UPDATE

*Update: So after a stressful couple of days worrying about the stupid clearblue, took another one today and I guess I’m pretty pregnant! Don’t know why the last one was negative, maybe I had a dodgy batch or maybe it had something to do with the fact that I only dipped the test for 10 seconds as opposed to 20 as I didn’t have the instructions on me 😳😅 Anyways, I can take a breath now! Until the scan that is, hope I get to stay pregnant this time 🙏🏻 *

After almost 3 years of trying, a round of IVF and a miscarriage in June, I got my BFP yesterday afternoon. It was glaringly positive! I was so happy. Took a clearblue digital this morning, just to see it in words, and it’s bloody negative. I was so sure it’d be positive, I mean all the other ones I took are. How is this possible? Last time I got a positive on a clearblue when all the “analogue” ones had a barely noticeable very faint line. Should I be worried? I can’t take more worry and heartbreak, the last few months have been so hard 😞 Has this happened to anyone?

I’m 11dp5dt/16dpo today. The first positive was from yesterday.
