me and my boyfriend have been having unprotected sex for about a year now, im already a mother to a 5 year old but its been hard for me to conceive since i havent been pregnant for 5 years. i usually get my period on the 28th every month faithfully. but last month i got it on the 27th, and today is the 29th and there is so sign of my period. is it to early to test? do you think i could be pregnant?
