Cramping 10 days before period

Hi all,

I’m looking for some advice or similar experiences from others...

We are currently Ttc with our second and for the last 2 months I have been getting period like cramping for about 10 days before period due.

Last cycle about 2 days before period due I had some light spotting which then stopped. I was convinced it was implantation bleeding as exactly the same happened with my 1st. hpt was negative and then started period 2 days late.

I am currently 5 days until due on period and have been having same cramps as last month. Normally I am very regular (2-3 days) and only have light cramping day before. My bbt is currently around 37.2 every day and was same last month.

Also this month I struggled to get a positive on a ovulation test. Think it was positive on 27th May as lines were exactly the same colour but was pretty close so not 100% sure.

I have a pretty anxious personality so am getting pretty obsessed with wondering why my cycle has suddenly gone all strange when never has before.
