Could I️ be? 😍🤞🏼

I️ got a positive OPK on the 11th, we BD the 11th & 13th. I️ have had a few symptoms like nausea, cramping, & achy legs. I️ have tested the last 3 days but they have all been negative. I️ never know exactly when my period is coming but I️ do have one every month. {Average 34 day cycle} My period last for 5-6 days. I️ think I️ am currently 10dpo. Thanks in advance! ❤️
