My husband and I have been TTC. I had my menstrual cycle Sep. 28- Oct. 4. We TTC on Oct.7 and the 15. Im pretty sure Im pregnant. Ive had sensitive nipples, tender breasts, moody-ness, pain in my lower abdomen, nausea, tender bleedy gums, constipation. And yesterday when I peed I noticed some spotting. Then today when I peed there was a brownish color on my toilet paper and I also noticed a small blood clot looking thing fall into the toilet. I also took a pregnancy test Wednesday that said negative and today said negative. Can any help?
