I had sex with my boyfriend without condoms and he ejaculated in me multiple times from June 9-13th. I got my IUD in mid May and had it checked before we had sex without condoms. I thought I was fine because on June 13th I started my period but then once my period ended I had spotting for an extra week from June 19th until the 25th which didn’t even happen after I had the iud inserted nor in all of the times I’ve had a period in my entire life but I just didn’t connect it to me having sex until the other day. For the last 5-6 days I’ve had nausea all day long and a complete loss of appetite. I have had cramping in my lower abdomen as well since about two days ago. I have also been tired to the point of beginning to fall asleep while sitting up and even taking a nap which is really rare for me, only when I’m really sick. I took a pregnancy test which was negative and when I looked later it changed to positive which I guess is something called evaporation lines? I’ve taken three more since then and two have been negative. One was taken this morning and the other two were taken last night and tonight so my pee was a bit diluted. I used clearblue. I’m just a bit in over my head and lost. My next period isn’t until mid July but would I be in the clear since I’ve already had one?
