Hi! I'm really hoping you can help. I've been trying to conceive since may of this year with no luck. I'm really confused. In May 1st day of my lmp was on the 23rd had intercourse two days prior, June lmp was on the 21st intercourse was a week or two prior, July lmp was on the 22nd and intercourse was from the 4th to the 16th and August lmp was on the 19th had intercourse from the 27th to the 1st of September. I took a pregnancy test yesterday, the twelfth which came back negative. Does this mean I'm not pregnant. I went to the doctor in July to see if anything was wrong with me and he found no cysts or visible problems. Wonder what could be the problem. I have been feeling a bit nauseous but i had all the other months with breast tenderness, only this month i have no breast tenderness and have been having mild cramps on and off for about a week. No spotting or anything.
