10 days late

Me and my husband are TTC. I have had an irregular period for the past 3 months. I have had my period in the middle of October and 2 weeks late got my period again. I have yet to get my period since November. My period is 10 days late. I have took two pregnancy tests this week and both were negative. I am hesitant to take another because it's such a sad scene knowing I'm still not pregnant. 😪 Any advice or suggestions would be greatly appreciated. Thank you in advance.
