Feel like I am driving myself crazy! Help!

So back in September I found out I was pregnant with my first baby, unfortunately it ended in a missed miscarriage at just 6 weeks. I opted for D&C as my body kept hold for a further 2 half weeks.

Anyway here I am again driving myself crazy taking temps and reading forums online!

Here is my chart from the last month. Temp went up today to 37 Celsius but I am getting BFN on tests! I had the same temperature raise when I first found out I was pregnant so maybe I am comparing to much to my last pregnancy?

I am due to come on on Tuesday and my cycle is normally between 26 to 28 days.

I have no idea what to think. What does everyone else think? Does it look like I have any hope?

I got a positive at just 11dpo with my last and now am at 12dpo.

I also have all the same symptoms as my last, backache for the last 3 days, boobs have gone sore in the last 2 days. Everything matches but just not the results am getting :( am going mad arnt I haha

Thanks ladies for any advice! Xx
