So I have not gotten a period since the first week of March I tested back in mid April and got a negative. Have been feeling very bloated for the past 2 weeks and this last week I’ve been feeling nauseous at nights. I’m scared to test again. Because I was very disappointed last time I got a negative. We weren’t really trying to conceive before I missed my period last month and when we got that negative we realized we were more upset about it than expected and began trying. I’ve also never missed my period other then when I was pregnant with my son so I was sure last time I tested it would be positive but it wasn’t 😔 so now I’m just afraid too test but another month has gone by and still no period. So idk what’s going on
