Hi, i gave birth to my second child in Feb 2011, and have not had a period yet, just a tiny bit of blood on 2 occassions. i am 33 years old and weigh 56kg, and am in general good health. i have been breastfeeding and taking cerazette, although i missed 1 day of the pill by mistake. over the last 3 weeks i have been getting pregnancy symptoms including headaches, extreme tiredness, tingly breasts and my tummy is bloated. could this be a side effect of taking cerazette? i did a pregnancy test which was negative, but i still have the symptoms described above. could i be pregnant and the result is affected by taking cerazette?
