I am so pleased I'm not alone 
I came of Micronor (mini pill) about a month ago now, have had one period (at 32 days which is longer than usual, I was 28/29 days when on the pill) and have managed to convince myself that I'm pregnant already.
Loads of symptoms, dizzy spells, nausea, cramps about a week after (what Ovia told me was) ovulation, headaches, tiredness etc.
Took a test last Thursday evening (first response) which was negative though kind of expected it as that was 5-7 days before AF due. Another on Sunday morning (yesterday), though second urine of the day, and only 30 mins and a coffee after the first, also negative.
I have now convinced myself that I'm not pregnant (despite us having sex 10 days in 14 over my "fertile window") and just want AF to arrive so that I know one way or another - due in the next 2-3 days, so we will see.
But I can't concentrate on anything, I have spent most of the morning recalculating when fertilisation could have been, implantation and when hCG could potentially show in a HPT (home pregnancy test).
I'm going mad and this is only my first cycle! I'm tempted to buy some ovulation kits now, but then think, well that would be a waste of money if I am pregnant!
I was obsessing even before we started trying, had potential dates in my calendar based on getting pregnant first time!
