Ovulation is over with about a week and a half ago, the last two days I've have egg white cervical mucus, tightening in my muscles in my lower stomach region, nipples are semi sore and I get dizzy often and nausous mostly at nightime. I'm about 8 dpo. 7 days left until period. Are these pregnancy symptoms I've never ever had pms symptoms so I rule that out and normally a week before af my back hurts but it dont. Could this be my month? If I test 4 days before af is due would I get a positive if I am pregnant? I've been taking prenatals for about 2 weeks now.
