Hey girls

I don't know if you remember me or not. I haven't had a period since coming off BCP in March. I finally went to see the doctor who gave me a blood test then prescribed some Progesterone tablets to help kickstart AF over a period of 10 days. I started taking the tablets yesterday..
Today after SMU I got a very dark positive on my OPK(I'll post picture when my batteries in my camera are charged) . I am wondering if anyone else has been in this simular boat? Is this positive just my hormones rebooting so the reading isn't valid? Or is this actually a positive? The line came up as dark as the control line almost instantly on Internet cheapie.
ATM I live in Germany and don't speak the language so it's a little hard to phone the doctor and ask them. and my husband doesn't understand what I mean in the slightest so he can't really do it for me ^^;
Thankyou in advance! Sorry if this is a dumb question >.<
