Going by the way the rash
has presented with discrete itchy spots, looks like it can be some sort of eczema
or it can be vector(bed bug) dermatitis
or...It doesnt look like it is something related to the minipill that you were taking....So you can practice some general precautions like....applying a soothing ointment like calamine
lotion over the lesions and keeping them clean ...and take some antihistamines along to relieve the itching ,,,but if inspite of these, the lesions continue to inrease, then consult a skin specialist for proper assessment and management...
Hope it helps
