Some advice please......

I am 42 and trying to get pregnant, I have had 2 miscarriages in the past 12 months and have been ttc since March this year. I have no idea when I ovulate and when I think I am the opk indicates I’m not 🤷🏻‍♀️ so like a lot of woman I pray that I ovulated and fertilised and good old aunt flow does rear her ugly head each month. This month however has me a little confused 🤔. According to my glow predictions I was due a period on the 12th of October but I started spotting on the 8th and then on the 9th it was a little heavier and by the 11th it stopped and then when I would wipe it would be a little brownish/pink blob, so I assumed this was my period even though it was a lot shorter than a regular period (average of 5days lately)

I thought I would humour myself and take a pregnancy test on the 15th and I thought I saw a vvvfl appear within the 10 min. window. I thought I was imagining things so I did another one 2 days later on the 17th and then again this morning on the 19th and again a vvvfl appeared.

I’m not due a period again until around the 10th November, could I possibly of had an IB and my vvvfl last could be the start something wonderful or am I going crazy and trying to convince myself and my eyes that there is something there even though it’s not 😔
