Hey ladies, Im not sure if this is the correct place to post this but, December 2014 I purchased a device called ovusense. Its a bit like a tampon (made out of a soft plastic) that you insert over night and it measures your temp on a digital monitor. You basically do this all month (apart from when AF is around). It then can predict your ovulation window. I was a bit unsure about purchasing at first, but when I received it and started using it I noticed it was extremely accurate (I had blood tests done from my fertility clinic to confirm ovulation at the time ovusense advised me). I ended up stopping using it as me and my OH had a holiday booked so we stopped TTC for a while and thats when I fell pregnant. I have not been asked to advertise this product (just incase anyone thinks I may be in contact with the company lol), I just thought it may be useful to some of you ladies. There is a closed Facebook group for ladies TTC using ovusense and there has been many pregnancies. https://www.ovusense.com/uk/ Please let me know if this post is not allowed!
