I am on my second shot and I am tired of the on and off spotting. If I get my 3rd shot in June, then I will have the presumed spotting/bleeding throughout the summer. At least I know what to expect. I want to switch to Yasmin but I want to know what the likely effects will be if I switch. If I am to expect very heavy or irregular bleeding for the adjustment period, I might just switch in August and get my third shot just for the sake of enjoying my summer. Any advice would help. I know that irregular spotting is normal but I am not fond of Depo.
