Hi everybody ! I'm new here and I'm 3 DPO and hoping I am pregnant. It's been so hard the past 2 years since my period is irregular. Any thoughts on my symptoms? . The past two days I've been getting externally tired. Staying up some nights until 6am! I know crazy right?. Today (3DPO) I woke up with tender breast took a nap around 11-3. Wondering if there's a possibility I can be pregnant. I get back aches as well ! Any advice will help. And I did have sex 2 days before ovulation and the day of.
