Problems with provera and famera please help!!!

The Mrs.
Ok ladies hopefully this isn't to long I just want to give all the info. Thank you in advance for reading and any answers you have to offer!! Ok so I have PCOS, as a result I didn't have a periods for a year at a time for 2 1/2 years. ( I was obviously concerned but was undergoing multiple Surgerys at the time from a bad accident and could barely afford the Dr appts. For those) I was finally able to see a doctor in October. I have had regular periods up till March from th bc he put me on. My husband and I decided to start trying on our own at this time with no luck. I went back to the Dr last Tuesday and was put on provera for five days that I started that night. Followed by the famera on day 3. But I forgot to take it so it was started on day 4 and I will take the last dosage tomorrow. My problem is aunt flow hasn't shown up.... is this normal? Has any one else has this problem? Could this be because I started famera a day late? Please any help is appreciated I'm very worried that there is something wrong and that this means I can't get pregnant.......
