Yeah I am not sure about using Pregnyl for conception so I am unsure on all of that but if its anything like it is when you are pregnant on it then it would be hard to find the symptoms becuase the hcg can trick you... I mean the hcg in what is created when you are pregnant and what gives you the pregnancy symptoms so I knew when I was pregnant before I did the test (I wasn't on pregnyl then) but since being on it, I don't know if its the injections making me feel the sore, engorged boobs, creamy cm, bloating, feeling sick and light headed... or it is a strong pregnancy. Kind of sucks but I guess the only way is the first scan...
So for you, the no show of a period would be the best way to know you are pregnant so I really hope you dont get it
