Had sex with a condom on the last day of my period, it didn't break, I'm still skeptical?

first off hun yes it is very unlikely to become pregnant if you are not ovulating me and my partner have been trying to conceive (only for 2 months now) but thats while im ovulating and im taking all the right stuff so you have used protection and he didnt come u have absolutely nothing to worry about. those symptoms are all in your head you do not start experiencing any symptoms until your 4 weeks pregnant and thats when you have missed your period than you may have a little morning sickness around 6 weeks. i would stop stressing because stress can make you sick and also your body can trick itself into thinking your pregnant and give you symptoms such as a missed period or spotting. so just sit back and relax.
