Ok I need some help/advice

(NO BASHING PLZ) So my and my bf/hubby had sex twice pretty much a week or so apart well the first time was like last week of June we did it he came wiped it off with his hand and we continued then second time we did it in July 6th and he told me he believed he may have came in me a little bit. this period calendar says I'm suppose to start my period tomorrow but the weird thing is usually a week or a couple days before I start my period I get symptoms it's coming on like mild cramps, my lower back usually is hurting, and sometimes I feel super bloated but I haven't felt any symptoms what so ever I took 2 pregnancy test one last Friday and one last night both came out negative but they were also the Hcg ones where assuming works the day of your missed period. I wanna know if I could be pregnant or not its driving me nuts plus we have a 12 month old so kinda scary to have 2 babies close in age if I am. or is it too early to get a positive result I will will happy either way.
