I have been having menstral like cramps for over 5 days now. I ovulated 5 days ago . I think. I was suppose to ovulation on the 22nd. But I had a cramp and took the LH test on the 18th and it came out positive. I still had mild cramps days after that but the LH test all came out more and more negative (the second line got lighter and lighter till it disappeared). We had sex on the 17th and 18th and 19th. Its now the 26th. The cramps are way more intense. My period isn't due till March 8th. Its always on time. Its like clock work. We have been trying to have a baby for 6 months now. Could this be inplantation? I dont have any other pregnancy symptoms. I'm not sick or feel tired. Just cramps.
