Me too. I am getting a lot of breast tenderness, cramping and spotting then AF. My cycles also are becoming a little erratic. They are 29days one month, 26, 29, 25. I just went to get my day3 labs and all my numbers are great. My next step is an ultrasound to make sure my tubes are clear, etc. I will be 41 in a few weeks. Another think that is new is for the last two months I no longer have ewcm around ovulation time or anytime for that matter. I am going to do OPK to see if I am ovulating anymore. If you dont want to use Preseed, I started drinking Salada Green Tea, citrus flavor, DECAF, each night before bed and within 3-4 days had a ton of ewcm. Try that. Good Luck.
I just turned 40 and I have been experiencing everything that you
have mentioned. I never experience any warning before af was due, now i get sore breast and mild cramping. I'm almost certain you will be just fine. Hang in there.
