Hi mga mommies, ask ko lang kung may mga nakakaexperience jan ng headache on and off.?? I'm 11wks 3 days and 1wk na ung headache ko on and off and this time 3 days straight.. I'm on bed rest for the past 3 weeks due to hemmorage but umuokay na xa based sa last TVS ko nung May 29..Sana may makasagot, okay lng kaya ito, normal lang kaya sa weeks ng pregnancy ko? di rin po ako high blood.. thank you so much..
