I started the pill a month and 3 weeks ago, everything was fine, few mood swings from pill, I had a light - moderate period from the 20th - 23rd.. A week later I started spotting brown/pink blood for 4 days, (On the 2nd of October I started taking a course of 21 antibiotic tablets due to tonsillitis) in total, this month I had spotted for 11 days on and off this month and didn't come on my period I was due for on the 22nd this month. I am slightly bloated and of course, worried! Would like to ask before consulting a GP.
