Lower Abdominal cramps, late period and negative pregnancy t

I have 13 month old baby and it was fast and easy to get pregnant and have her. I got pregnant with our first try and I had an easy pregnancy and an easy delivery.

Now my husband and I have been trying to get pregnant for the last three months, but this time it seems to be a little harder. Ever since we started trying, I have been getting lower abdominal cramping two weeks before I expect my period. They are very painful cramps.. I thought of perhaps it's an ectopic pregnancy or implantation, but then I ended up getting my period and the cramps went away until two weeks before my period.

I have a history of irregular periods, so it's not a new thing that my period is late, but these cramps are. They feel like menstrual cramps. Sometimes these cramps intensify during sex and when I wipe after sex, there is light spotting with my husband's semen.

Now we are in our third month trying to get pregnant, and my period is late one week. We took a pregnancy test last night, but it came back negative. I am very confused about what is happening to my body and the cramping. My last period was January 30 2007 and we are now in March 10, 2007

It would be great to get some feedback and advise.

After you have a baby, your body changes especially hormonally. It is possible this cramping you are feeling is cysts (which form around the time of ovulation) or that you are feeling ovulation (I personally do not understand that but some women swear by it). I would talk to your doctor. Until you have been trying to conceive for 12-18 months usually doctors won't prescribe or do any tests for infertility just yet.
