Thanks Greenstone, that's made me feel a bit better. Though have come to the realisation that if my nipples grow much more, I will have more nip than actual boob. A bit freaky.
On the spot front, my face has surges of clearness (yay!) and surges of pizza-face days (booooo) but my back is DISGUSTING
I've never really had a spotty back before, but for some reason pg has given me more spots than the average Dalmation. Yum.
I am SO EXCITED however, because my DM has just announced that she's booked us a mother-and-daughter trip to a spa in two weeks time and it's in Barcelona!!
Even better, it's a gift from her for her first blood-related GC and she hasn't asked me to pay (which is good, because I couldn't afford it). Is this too much to accept, do you think? I'd really like to go, especially as DP threw a tantrum over it when he found out even though he's going to be on golf tour for those days and wouldn't therefore be seeing me anyway. (He promptly zipped himself into his flies after shouting at me. There was skin missing, blood & everything. Can anyone say karma...?
) I am aware that this makes me a spiteful and horrible person, but I can live with that. Anyway, to cut my ramble short, if I go I'm hoping sunshine will work its magic on my back.
Oh, also Greenstone, I would seriously consider taking the ABs. They can give you some that are pregnancy-safe and well tested. For a skin infection, which is what folliculitis is, you would most likely be prescribed a penicillin-type AB. They work by preventing the reproduction of bacteria and basically causing the organisms causing the infection to become extinct. Because they target specific infection sites, they are safe to use during pregnancy - your baby is safely sealed in the amniotic sack, it has absolutely no exposure to the infection your ABs will be targeting, so would be safe from their effects 
An untreated infection, on the other hand, has every chance of spreading. Folliculitis can lead to problems like cellulitis, damage to the lymphatic system etc. (Not saying that it will, obviously, but that it can.)
Maybe explain your concerns to your GP? I'm sure they can explain it a lot better than my babble!
