Hi and welcome to HCM.
Cramps arent usual symptoms of pregnancy
. If she didnt have period you should wait 2 weeks after it and then do pregnancy tests
. It is hard to say now is she pregnant. SOmetimes is more than 6 months needed for hormonal
stimulated ovulation and succesful fecundation. I wish you luck,just be patient and tenacious,there is no need to hurry. This therapy can cause unplesant symptoms such as cramps, vaginal bleeding etc. but this cant be avoided. Wish you good health.
