I totally understand you worries! I was on the pill for 10+ years and when I got off I was terrified of what might happen (new acne, horrible pms, morph into a she-wolf

). I was on much longer so the adjustment took a while but I think the body finds a way to get back into balance. A year on the pill and your body should recover fairly quickly.
Based on the link to the pic and what had been written there I would side with what many people responded -- that this does not look like 'typical' acne. Possibly perioral dermatitis or a fungal issue. Tooth paste, mouthwash, and even lipgloss can aggravate skin issues around the mouth. Also, does boyfriend/husband have facial hair or stubble? In my experience, when my husband has too much stubble or a dirty beard it really rashes up my sensitive skin.
Birth control pills can help alleviate these pseudo-acne conditions to a degree only if they manage to limit your sebum production (by controlling your hormones of course). Anti-biotics I personally dont like unless absolutely necessary-- been down the cycle of antibios & yeast too many times to count-- and woman to woman I know you understand the troubles it can cause.
If you can track your breakout with your cycle then they may be hormone related. Hormone tests wont show that--only show if you have whacked out levels and were growing facial hair or in early menopause. There is a good board here on hormone related acne and treatments you can adjust to fit your cycle. Spiro is great but needs an RX. Spearmint tea helps. DIM can help as well. IT just depends on what you identify you hormone issue as being (i.e too much estro, too little estro, or too much andro/testo, or a combination). Delightfully confusing, huh?
I still say see a derm if you can. The pics do not look like 'acne'. If it is fungal there are prescription and non-prescription treatments that are very effective. Also want to rule out any other causes-- I will just cut and paste this part: Good Luck!
Perioral dermatitis has even developed in patients who use inhaled corticosteroids for asthma or hay fever, if they allow the medication to drip onto their skin.
It is thought that transfer of saliva to the skin around the mouth may play a role in perioral dermatitis.
Researchers have attempted to link perioral dermatitis to infectious organisms such as
Candida yeasts,
Demodex mites, and fusiform bacteria, but no conclusive role for these organisms has been demonstrated.
