My boyfriend and I have sex pretty often (honeymoon phase) and I might be pregnant. I missed my period last month and am late so far this month. I have gone 4 months without a period before and then had 3 days twice in a month after. I have always bought pregnancy tests and them be negative. This time I feel nauseous, some cramping, back pain, and my boobs are sore. I just don't want to get my hopes up buy it again and find out I'm not.
