We've been trying to conceive since it miscarriage in May. It's been so stressful every month when my period is due to find out we're not pregnant. I started taking folic acid in January, having intercourse everyday.. No period showed on 6th February.. pregnancy test come back negative, another one did and so on.. Did a test on Friday a tesco one.. 2 faint lines.. Another did.. So I bought anther clear blue which shown 5 weeks pregnant! Couldn't stop smiling happiest feelin in the world!!
