i never took infertility, but it did take 9 mos. for us to conceive my first baby due to irregular cycles and when i was preg, i had the most positive pms symptoms too (cramping, headache, bloating, etc) but I was indeed preg. My second preg. was a complete surprise (we were doing the rythem method and all was working great until I got sick and my cycle suddenly changed) and then too I had what I thought was pms but yet it still seemed odd. Took the test and yes, I was preg. My dr said that when many women get sick (the type of sickness can depend by the woman, but for me it was flu-like sick), it throws their body into "baby-making overdrive" due to mother nature wanting to reproduce in case you can't get over what ailes you. She also said that many women who have a prob getting preg the first time or two have no prob afterwards because the body is more in tune with conception.
Basicly what I am saying is it is very possbile you are preg. It is also very possbile that you just did not ovulate this mos. and missed a period. The only way to be sure is to do blood work. If the preg. is a tubal (and I sure hope not), the home test may come back neg. because you are not producing the hormones to supply a uterine preg. The home test may also come back neg. just because you are not far enough along yet either as was my case the first time I took a test w/ my second preg. I wated and week and the 2nd came back totally positive!
Hope all works well!
Best of luck whichever way the tests fall!
