mind playing tricks

Melissa
So, I've got three kids, two from a previous marriage... I had those kids when I was 19 & 22... neither were planned, but no fertility issues.... fast forward thru a divorce and meeting my now husband and getting married... (both in 2014) I had a surgery in April of 2015 to remove a cyst on my left ovary... during surgery doc noticed my tubes were blocked.... so in May I had an HSG done... results showed I have a rare tubal condition/disease where I have nodules... doc told me "this is something we learn about in med school and never see again" there's little to no information on it (salpingitis isthmica nodosa) and I'm not sure if my tubes will eventually close completely, but that's why my hubby and I were having such a hard time conceiving.. we started clomid as was the cheapest route, well it took! Baby girl was born on hubbys 30th birthday in 2017.. 
We've been trying for the fourth and final baby for 2 months now. Clomid again.. first month was 100 mg this month was 150... this month the "symptoms" are going to drive me straight up a wall.... I have had a splitting headache for 2 1/2 days, for 2 weeks after I ate anything I would get very nauseated, now the past two days, I don't even have to eat anything.... nauseated most of the day.. boobs hurt, but not extreme pain, they feel heavier, my hubby has pointed out that my nipples have been hard a lot lately... my sex drive is gone. Certain smells make me want to vomit... 
I am supposed to start (I'm assuming, periods vary and idk when) Sunday, so I was going to test on Monday... but am I going crazy? I keep telling myself it's the clomid because I'm getting seriously bummed with all the negative tests.. 
Thanks for taking the time out to read this
