Jessica
Hello I'm Jessica from Wolverhampton uk 
I have a son who is nearly 6 from a previous relationship nd my partner also has a son who is nearly 6 from a previous. 
Me nd my other half have been trying 4 13months nd no sign of a pregnancy 
Finally Drs r sending me 4 bloods on the 16th to c weather I'm ovulating. I have very short cycles since my miscarriage 13.7.15 at 10weeks my cycle range from 18-22days 
Has anybody else ever had problems ovulating if so wat happened and did u go on 2 have a healthy pregnancy???
