Period is supposed to be here today but it's not. And I'm having lots of creamy mucus. Since shortly after ovulation my breasts have been sore and heavy but my nipples are OK. With my first baby, tender nipples gave it away that I was pregnant. I was having my usual pms cravings but no cramping or back aches as usual. Do you think I could be pregnant? How did you know? I don't want to take a test as I only have 1 left. I'm hoping I'll wait a couple days. ..if I can hold off that long.
