Is it common to get flu like symptoms in early pregnancy?
E.g. Constant sneezing chesty cough sore throat ear ache head ache, hot & cold, sweating and very sleepy.
Currently a week late on my period but they've been irregular recently. Having sharp shorting pains in the lower stomach too.
Not sure whether to waste money on a test because my period will eventually come or if I could actually be pregnant.advice please? short length mother of the bride or groom collections
