Need help - losing faith :( and getting down!

Jo
Hello! Been trying for about 18 months now and getting extremely down. 
​I had a HSG test on day 12 of this cycle so I was hoping I might conceive this month with cleared tubes! Or get my cycles back to normal. They've not been too bad but was hoping they might go back to 29-32 days.
​Anyways here's my charts and I haven't come on yet! So I took a test this morning and it said negative, I keep gettin some pains near belly button and cramping also feeling sick, had this for over a week now....
​Anyone give me some advice or just try and cheer me up?? :( x
