False positive?

Chelsea

Ok so I have never posted on here before but need some help I took both pregnancy test on Sunday exactly 14 days after me and my long time partner had unprotected sex. We are not actively trying as we have 2 kids right now so any both test showed the line with in seconds (rite aid brand tests) Sunday night I took a first response test it was negative Monday morning took the same test (it was a 2pack) and again it was negative. Monday early afternoon I bought a few dollar general pregnancy test and they were all negative. I will add that Saturday threw Monday I have what I think is morning sickness bloating tingling nipples and fatigue.....
