I would be 7 weeks today and I took a blood test at 6.5 weeks and it came back negative. I had early spotting 18 days into my cycle and right after I had swollen breast that were just a bit tender. Then came the fatigue, headaches, nausea and cramps . Mind you this has continued and hasn't stopped. Matter fact my abdomen is very tender and backaches accompanied. Headaches not as bad but pinching and cramping as continued and constantly. My breast are tender sore and swollen and have went up a cup size. I'm Constipated if I don't take vitamins with stool softener. I only eat fruits and vegetables not really any meat other than seafood. Basically, I feel pregnant since symptoms have continued for 3 1/2 weeks after bleeding and spotting occurred. Last normal period was April 4-8th and early blessing occurred on April 24th and ending on 28th (only bled for 2 days) and spotted the rest .... has anyone had negative blood test and still been pregnant?
