yes those are both pregnancy and progesterone symptoms. i am on the prog suppositories and had all those symptoms. the only different thing i got befor my BFP test was i out of the blue vomitted for no reason at all like 2 times one day last week. i think it was from my body having hcg in it all of the sudden.
How far into the 2ww are you?
progesterone can have the same symptoms as pregnancy. If she started feeling this way right away, right from the start, then it's most likely caused by the progesterone. If she starts having these symptoms later in the 2ww, and the symptoms increase, ex. the breast pain increases every day, then it could be a sign of something else.
good luck!
