I'm currently 4 days late on my cycle. My husband and I are trying to conceive. First day of my last cycle was 12/25. We had intercourse the week of the 6th twice and then the following week once. Since these last 4 days I have taken 4 pregnancy test that came back with faint positives. Today I'm currently spotting a bit. I'm just worried because I keep reading everywhere that you won't get a positive test until implantation bleeding and this could be a chemical pregnancy. Any opinions or advice?
