I am on my second week of a 10 week cycle. First application and week went by very well with no problems whatsoever. Second shot was this past Wednesday (its Sunday now (4 days later)) and it feels as if I have a third bum. There is no bruises or anything but there is a serious swelling going on at the entrance site. After the first application it was sore but no swelling, this however is totally different and is starting to worry me. Question: Should i be worried and am i screwed if the swelling hasn't gone down by now? and what may have caused this? Thanks for any help ya'll can give....
