Have had 3 normal pregnancies, 3 live babies. Only took one time having sex each time and boom... pregnant (poor other half he he! ) Each time i knew I was pregnant at around 4 weeks before any tests as i had definable symptoms. Had slight bleed at 11wks with no.2, just spotting really, all was ok and was told no more hiking with heavy loads ie: toddler and no more heavy lifting. A week and a half ago again came up with all the signs of pregnancy. Didn't do a test as was in denial and in small town didnt want the whole world to know when purchased test. But signs there thick and strong. Woke up this morning with heavy bright red bleeding... and period pain.. hmm maybe no. 4 wasnt meant to be.. partner has had snip as we are too fertile.. and maybe he wants more regular sex. More than the once a year for a baby anyway! Will see how it goes..
