from A to B

About three weeks ago I got the Paragard IUD. So thrilled! I've been one of the lucky women to have, literally, no side effects except a cramp or two and a day of spotting. 🙌🏾 BUT something I have noticed that is different (my boyfriend commented on this as well!) I think my breasts have increased in size? Wondering if this is something other women have experienced? My breasts have been tender and I think it's because my bras don't fit as well as they did a few weeks ago. Is it worth getting a new bra fitting or will this side effect decline over time?
