Headaches help

💙 • Married, Mommy to 1 + 1 on the way 💗

I’ve had the worlds worst headaches the last two days but don’t want to take Advil at the risk of being pregnant (I still can’t test for a week). I’ve also had on and off slight nausea and sore breasts (usually only lasts 30 minutes) so hopefully it’s a good sign 🤞🏻 but these headaches are killing me. Any advice on getting rid of them? I’ve tried cold wash cloths and a hot bath but nothing has helped so far.
