New to this

Hey y'all! I am new to the whole ttc stuff (lots of abbreviations and things to learn!)
​ 
​I have PCOS and I haven't had a natural period in over 2 years. 
​ 
​My OBGYN gave me progesterone 50 mg 2x a day for 10 days to bring on af and I just stopped yesterday. I haven't really had any bad symptoms from the med besides being tired and a little bit of nausea but today I woke up and my nipples are so sore! Even a bra hurts but it's not all over by breasts. 
​ 
I've taken Provera before and it made me miserable but it also made my breasts hurt so bad I couldn't wear a bra. Today's feeling is different.
​ 
I'm pretty sure I'm not pregnant but I will take a test this weekend.
​ 
I guess my question would be if this is just a normal reaction to a spike in progesterone. 
​Thanks!!
