Constant headache?

Has anyone experienced a constant headache that never goes away and if so it’s only gone for maybe 3 hours and comes back during early pregnancy or pregnancy in general? 🙁 also if you bleed exactly a week before your period and it’s the slightest bit of pink blood when you wipe and after that you never bleed again that implantation bleeding too right? 😌 haven’t had a period in 30 days lol
