Couldn't find what you looking for?


The first date of my last period was the 21st Feb, I am having regular unprotected sex with my partner (trying for a baby for 2 years). Stupidly I had unprotected sex with an ex on the 25th Feb. I've now discovered I am pregnant. I am really worried that this baby is not my partners. Can you offer some advice please


When did you have sex with your partner? Do you know when you ovulated?

Assuming a 28 day cycle, you'd ovulate around day 11-16. Sperm can live about 5 days in your vagina. So, if you had sex from about day 6 of your cycle on then there is a possibility it was your ex. You said day 4, close.

The only positive way of knowing is via DNA.

Hope it helps.
