Did you have any bleeding if you got pregnant whilst on he pill? I have been on Cilest for years and always had he same sort of period on it. 4 days of medium flow, a day or do at the end of just coloured discharge really.
Last period was very light, only lasted 3 days as well. I put 2 packs together then to skip a period while abroad on holiday and period was due this week. Well its even lighter this time. No actual blood, just darkish discharge. I don't even really need a pad! Just 2 days or so.
We have completed our family and I am nearly 40. I missed 1 pill during last couple of months and took it and the next one together. The instructions say it will be highly unlikely to get pregnant missing only one in the month.
BUT.... A couple of months ago I was put on some anti inflammatory painkillers for back ache and they kept upsetting my stomach so had to come off them. (diarrhoea but no vomiting) The gp didn't tell me the tablets could affect the absorption of the pill when she prescribed them, I only found that out myself when I looked at the patient information leaflet about the diarrhoea.
I am now a bit worried I might be pregnant although no other symptoms. Although stomach looks a bit bigger - looks like its wobbly fat though rather than being swollen! I am too scared to POAS and feel like a teenager. 
Seriously, how likely is it that I might be pregnant?
