Am i overracting?

Its been about 2 or 3 weeks since my bf and i last were intimate. Ive clearly stated that i wanted some but he hasnt even attempted to touch me. Mayb bcuz wen he gets home from work ive been asleep but thats never stopped him from wakin me before. Anyways i asked today why he told me hes been tired which he has been workin alot but 3 weeks in and no attempt to even touch me idk at this point its bothering me hurts a lol. I feel like mayb he tired of having sex mayb bored or i dont attract him i even thought mayb hes scared to hurt me or the baby but too long already. I knw hes not cheatin. I havent gone thru his phone he gives me no reason to think he has somethin goin on. but the other day i opened the web browser and pops up some porn can i be overreacting or my hormones am i wrong for feeling this way? Now cuz i brought it up i dnt want him to have sex wit me cuz i will feel like its forced like i had to say somethin? Anythin help :(
