Trying to conceive after 2 miscarriages

Hi me and my partner have been trying to have a baby for just over a year now we had 2 miscarriages last year one on the may and then another in the June. However I don’t seem to have fell pregnant anymore since then. I have been to see a fertility consultant and had all of the tests but they have all come back normal so now I have until the summer to get pregnant before I have to go back. I really want it to happen naturally so I have just bought the ovulation tests have these worked for anyone?
