Ok I had the implant removed on the 28th of March and had unprotected sex with my OH on the 29th ... my periods have always been regular even on the implant but now il 6 days late, feeling nauseous, sore back and tired but been getting on the tests...i never got any of these signs with my son as i fell pregnant on the pill .... is it possible to get pregnant this quickly .... I was at the hospital on the 3rd April with a UTI and they said I wasn't pregnant but i wouldn't have even been a week so would their test have been wrong to? I had a light bleed on the 16th April but it went that night (i never had spotting with my son so don't know what its meant to look like) this is killing me not knowing has anyone had similar experiences... im just at the point i want to know now x
