Had some light ‘one off’ brown bleeding on Monday 13th. Thought it was the start of my period bang on 29 days, but then no further bleeding. Realised I was 12 dpo, so did a strip pregnancy test, showed positive. Did a Cleablue on 13dpo (15th January), also positive. Have had some light (red) bleeding and cramping since 18th January evening. Preparing myself that it is a chemical pregnancy. Not sure when to test again, how soon after a chemical pregnancy should I expect a negative on a pregnancy test?
