My bae and I had sex on the 28th of March and we were feeling a bit iffy about it afterwards because he didn’t use a condom (he did pull out but he precummed) and I don’t take anything for Birth Control and since then ive been feeling lightheaded, nauseous, very very hungry, bloating and what not. My period was 18 days late and they always last 7 days its normally just a medium flow not heavy and not light but it started off heavy getting lighter and lighter and by day 5 it was finished. I don’t get cramps on my period but everything else has me nervous. I’ve taken two tests and both were negative but one was faulty. This has been worrying me to the max
