My periods returned 3rd December 12 after having my baby in April 12. It was considerably lighter and less painful than post pregnancy periods. I had unprotected sex on 6th January 13 and then my second post pregnancy period came on 7th January 13. I am still breastfeeding but my baby is now weaning and eats solids and feeds less from the breast with supplemented formulae once or twice a day. My question is is it possible at all for me to be pregnant? The period following the intercourse was again light- medium flow and not too painful. I had cramping on 20th - 21st Jan and it was quite uncomfortable and had a break out of pimples and moodiness around this time. I assumed it was ovulation pain but am now wondering if it could have been implantation cramps which I had with my first conception . Perhaps it is just all my body returning to fertile and my periods are going to resume as usual but I have some symptoms that have got me suspicious. These include nausea, one bout of sickness after a car journey, extreme fatigue and moodiness/irritation. I also have been more tearful than normal and seem to have extra saliva again. Now today I have had to un zip my jeans even though I have not put on weight?! Could all this just be my hormones changing back or am I at all likely to be pregnant? If there is a possibility of being pregnant, when would a test show as positive given my dates of intercourse etc? Thank you in anticipation for any answers you can help me with.
