@Irwine I am so sorry to hear this. I had 2 when trying for the first time and I was devastated both times. It was the false hope and loss of a dream that hurts the most. It's surprising how much you plan and get excited for a baby in such a short time of knowing.
To share a positive and give you some hope this is how my story worked out:
As I said I had 2 chemical pregnancies before I was pregnant with DS (now coming up to 3)
I had a chemical pregnancy in the November (I felt "pregnant" and had a positive test then lost symptoms and began bleeding, light spotting at first before becoming like a normal period and then a negative test)
Then had a normal period in December (after a normal cycle which I was shocked about)
Then already in January I had another positive test! Unfortunately this also resulted in a chemical pregnancy.
But only the next month in February I had yet another positive test and this was my DS who stuck and is now nearly 3! 
So just know it shouldn't stop your ability to get pregnant again soon so don't lose hope (I definitely did after the 2nd CP but there was no need!)
I am now currently 29 weeks pregnant with my second who is a little girl, no chemicals this time but 6 months of trying before we got a positive.
So please hang on in there as I know at the time I felt like I'd never have my little family but the time has flown by since those days and here I am now with 1 and a half babies lol
There isn't a great deal of support for chemical pregnancies I found, I felt at the time silly for being upset as it was so early (I was told on more than one occasion it was "just an egg") but do allow yourself to grieve as it's still the loss of a dream and when TTC every week and month can feel sooo long!
Sending love xxx
