I am 42, I have 2 girls 16 & 17 and am newly married (4 months) I had unprotected sex this month on the 1st had period (at least I think it was a period) on the 11th 3 days before I expected it, it wasn't light but also not as heavy as usual, I had unprotected sex again the 22nd, off and on all day yesterday my nipples have felt hard, sore and chilly and my undies have felt wet, I checked my cervix a few hours ago and there was this blob of mucus, more than I have ever gotten before when I checked, it was part clear part milky white and watery,could I be pregnant or is it just ovulation? could my last "period" have been implantation bleeding?
