light bleeding, no cramping, full symptoms of pg

My husband and I had been trying for several years to get pregnant, been through doctors telling me I can't have children, have miscarried three times, yet this is the first time I've had all these signs, started light bleeding tonight, no cramps, just a bit of back pain in lower back. PG test I took on May 1,st stated negative, yet even my nipples have been extremely sore for 2 and a half weeks after using the "kit" that is just like doctors use for artificial inimination to help us concieve. I know I do ovulate, and that when I did on april 15,th my temp was up for 30 minutes and that's when we did the kit. I have been craving weird foods I usually never eat, swelling of the breats and starting now of changing color of nipples as well. Also have felt the pinch that happens when the sperm makes it through which I didn't know about till after did the kit, and have had my left side near my tummy swelling a bit and sore for the past weeks. I am so confused and could use anyone's help that's been through this. Please, if your going to tell me to see a doctor, I already have plans too. I just need advise if anyone else has gone through this before. thank you

My girlfriend has the exact same symptoms and has not gone to the doctor, this is an unplanned pregnancy, and her prognosis on getting pregnant is similar to yours, said to be impossible, she's had problems all her life. i would like to hear about how your experience turned out or any other information anyone else can provide. thanks very much
