Hi ladies, need some help and reassurance please. Here is some background. My DD2 is 16 weeks old and due to rapid degeneration of my pre eclampsia she was born in v poor condition by crash section at 34 weeks. In fact it took 16 mins for them to get her to breathe or to get a heart beat. She was in ICU for 12 days but fortunately at the moment doesn't seem to have suffered any lasting effects. However DD1 was also born 4 weeks early by emergency section after getting into distress because of me suffering pre eclampsia in that pregnancy too. DP and I have talked a lot and decided that its too risky for me or any potential future baby for us to have any more children.
So on to the reason for my post. I am exclusively breastfeeding DD2 on demand and have been since she was about 6 weeks but previous to that was expressing for her. I had the depo injection on 6th september and DP and I have had sex only twice since she was born. Once just after the injection and once late last week (sry if tmi) I have had a 3 or 4 day bleed last week too. However I have felt quite poorly the last few days and today have had chronic nausea and a headache all day. Also suffering indigestion which is something I only ever experience in pregnancy. We are in the process of buying a new house which has been quite stressful so am not sure whether its stress/anxiety or whether I could be pregnant. If I am I don't know what to do. I do not believe in termination but I really don't want to take the risk of a third pregnancy. I know the only way to be totally sure is to POAS but what are the chances?
