My lo will be 2 in July we occasionally have sex maybe once to two times a month I took a test around a week ago one of the clear blue early testers it had an empty circle also took an ovulation test bc when I was prego w my first it said I was ovulating and I read ovulation tests pick up hcg both empty circles although my ovulation test is bout 2 years old not sure if they still work... I am never late on my period just confused as to what is going on with my first I was 5-6 weeks along before I realized I was pregnant and so excited and pretty sick and tired at this point I don't have pregnancy symptoms or period symptoms..,help!!! Ps a few days after we had sec I had a streak of blood on my discharge but I'm not sure I was ovulating or if he went inside me.. Opinions?
