Trying to conceive a second baby. I had possible implantation bleeding for 4 days (never had with first born), been eating more than usual mainly sugary food, was sick after eating rice and again after changing my son's nappy. Been getting hot at night time. Pulling muscles easily in my back and shoulders. Getting moody or emotional on and off. Feeling tired on some days. The only sign I had with first born was sickness and a wisdom tooth growing. I am now growing another wisdom tooth. My period is irregular making it difficult to know when to test. I am on day 42 of cycle. Has anyone had half a faint line and turned out to be pregnant? I keep getting negatives on cheap tests and faint positives early response. I have a clear blue digital but should i go buy another first response and test again tomorrow before using clear blue? Is it possible I am really pregnant? Been trying for 7 months and have been gluten free for 4 months after been diagnosed with coeliac disease.
