So I had only started taking the pill at the start of this month (the 7th January on the 1st day of my period) and on the 3rd and 4th day I forgot to take my pill, so I missed 2 pills. I took them both and then that night I had my 5th pill like i normally would because I take it at night. I have had my period for 3 weeks and 3 days, with a really light flow. Is this normal? Please help
