My periods have been usually regular. I was expecting my period to come 5/13 and all that came was one pea sized spot of blood and that was it. It is now 5/22 and since then, no other blood has came and I've taken 3 home pregnancy tests and all have been negative. I've done some research and some say the same has happened to them and for some they didn't get a positive the whole time but they were pregnant and for some it took a long time into pregnancy to finally show a positive. Should I wait a couple weeks and take a hpt again or what? I've had some random nausea through out the days since I ,missed my period, had some cramps in the right side yesterday, and have been more tired lately.
