I'm new to this . This my first month I actually ttc . I tracked ovulation and I used pressed how ever I took 3 first response 1 was negative and the one from yesterday and today had postive lines I know I ovulated on the 9th I've taken clear blue digital and says not pregnant I'm 4 days late on a.f but my question is can I trust first response ? All my test are fmu I just want lines to get darker how long should I wait to call a doctor or something I guess I'm just Nervous to know im not pregnant
