I am unable to go on the combined pill due to migraines. However I am slightly concerned about the progesterone only pill because I already have acne. I know this type of pill can make acne worse so I'm just wondering if this is a definite thing or just possible? Also I'm concerned about the weight gain. How does the pill make somebody gain weight? Is it water retention or does it increase your appetite? Thirdly, is it less effective than the combined pill (is pregnancy more likely with progesterone only than combined if I take it at the same time every day)?
I'd really appreciate some advice. Thank you!
