There is always a possibility of pregnancy when you have unprotected sex. You can take a test one week after your missed period if you do miss.
My friend had her period on the 7 of febuary and it stop the 12 and she had unprotected sex the 14 can she be pregnant or how long show she wait b4 she can take a pregnancy text
Hello there Trudy, she should be able to take a pregnancy test in the next two weeks which will indicate the possibility of being pregnant or not.
So, I had my period on January 15th and then during sexual intercourse on Jan 26th, I had a good bit of blood that came out of me during the intercourse. It went away and then on January 29th/30th my period seemed to start again. Do you know why this would have happened and when I should expect my next menstrual cycle. I’m totally confused and even more confusing is trying to find out when I am fertile as we are trying to have a baby.
Sometimes minimal bleeding is normal, it is a shift in cycles. Tracking your periods can truly help with this.

Hi Chubbs. There is always a chance of pregnancy when having unprotected sex. According to the information you provided, your most fertile days would have been Feb 3-8. Best of luck to you.
Hi, I was on clomid and was given the 2,4,5,7 of February to have sex with my husband as we are trying to conceive. On the 18th of February I had some bleeding, not so much though and it lasted for 3 days. I was supposed to get my menses somewhere from 24th since I have irregular periods. Can I be pregnant ? What is happening to me? Please help explain
Hi there. Pregnancy is always a possibility. Are you sure the bleeding was not your period? Since your periods are irregular, it showing on the 18th would not be impossible. If you think you may be pregnant you can take a pregnancy test or see your doctor. Wishing you well.
I use to have a 26days cycle and I started my last menstruation on the 21st of Jan and wanted to know my ovulation period on the 15th day after several days of testing with my prediction kit got a smile on my clearblue I.e LH detected.

Along side my prediction kit am using folic acid +B12 all to boost my pregnancy. Please can someone should advise me
Hello there. According to the information you provided you are most likely to ovulate between March 5 and 10. I would suggest that you continue to do what you’re doing to keep track of your ovulation along with consulting your doctor. Best of luck to you!

Hi I’ve been having irregular periods sometimes I get them some times I don’t . I started my period February 24th and I should be done by the 28th or 29th . also I don’t understand how the menstraul cycle works and when do I ovulate. I also have been trying to get pregnant but for some how I can’t . my irregular period started almost 2 years now I believe so and its weird I mean there’s times I start it the first week of the month or in the middle of the month or just the end of the month . How can I stop that from happening? I was never like that before .. Please P.M . Thanks
