So I ordered a few home pregnancy test and they came in yesterday I am at this point almost a week late.18dpo Tested this morning and it came back negative which is kind of a shock. So I'm all going okay AF is just really late If I haven't started in a few more days I'll check again but then I looked at the box that the test came out of and it say Exp Date 2021-6-30 so it exp in June. Just wondering if I should say this test is mostlikly wrong and test again or if the Exp Date doesn't matter I haven't been pregnant in over 7 years so...🤷‍♀️
