Period started 01/8 ovulation 13/8 sex between 11-14. cramp, lower backache, feel sick, bloated, usin toilet often, tired, tender boobs am i pregnant?

Maybe: If you had unprotected sex around the time of ovulation you definitely could be pregnant. If your period is late do a pregnancy test and repeat it in 3-5 days if it is negative to know for sure. Urinary frequency, lower back ache, fatigue, and cramping could also be symptoms of a UTI. If the test is negative or your symptoms worsen, you need to be seen. Hope this helps.
