So I have 29-30 day cycles and my periods are pretty regular . I had sex with a condom on day 4 of my period and he didn’t cum and it lasted no more than a minute. It was a mistake I realised as soon as we started hence why it didn’t last very long. Then I had sex with my husband all the way throughout my cycle unprotected and he ejaculated inside me every time . I’m now pregnant and I’ve been for a scan and the sonographer has given my conception date as what my normal fertile days would be in my cycle . I’m just stressed out and worried because I’ve made such a mistake
