I’m 9 months post partum and me and my partner had unprotected sex after a few too many drinks for the first time since I gave birth. I’m not entirely sure when my last period started as they’re very irregular and I didn’t keep track of when it ended stupidly. It’s been 2 weeks exactly since the unprotected sex and we go on holiday in two days so I decided to test just to see. I did a strip test early this morning and I think I see a very very faint line. Then I bought two cheap tests and again I’m sure these are faint lines? They appeared within 5 minutes of the tests but then I did a clear blue digital test and it said not pregnant? What do we think
