Really trying to not let what I hope are pregnancy symptoms get to my head, but it's getting hard. I just feel different, I'm nauseous at random moments, I can't stand olives any more, I'm exhausted almost all day long, I'm crampy, back pain, and I feel like my sense of smell is enhanced. Something else I find weird is I have been taking OPK since April 20th, right away got a positive test then they started fading. For the past 6 days I've had positive tests. Can ovulation test pick up a pregnancy hormone? Praying for a baby since July and have had issues.
