This means that a tiny fraction of women do have a small chance of becoming pregnant from unprotected sex during their period.

Early signs and symptoms include implantation bleeding or cramps, which can occur 5–6 days after the sperm fertilizes the egg. Other early symptoms include breast tenderness and mood changes.

Can a 50 year old man get you pregnant?
By ages 46 to 50, the success rate was down to 32 percent. And men over age 51 were able to facilitate pregnancy just 30 percent of the time. “This drop-off will also be related to the maternal age and this decline in pregnancy rate becomes quite dramatic over 35 years for a woman,” Morris told Healthline.
Can a 48 year old man get a woman pregnant?
A new study shows that the age of the male partner can have just as big an impact on fertility and the time it takes to successfully conceive a child as the age of the mother. Researchers found it takes up to five times as long for a man over 45 to get a woman pregnant than if he was under 25.
