ok here goes.... Me and my fiancé have been trying to conceive for a few months, my period was due to come on the 13th of July.... 3 days before I had a tiny bleed that lasted barely a day, I presumed it was my period. For the past week my boobs have been unbelievably sore esp my nipples, I have back ache, I had what I thought might be a cold coming on last week, headache which has lasted 5 days now and my lower tummy feels tight and not as soft, I've also had a quick weight gain in the past week. The tests I've done have all come up neg could I be preg? And have I tested too soon?
